Pfx

The encryption algorithm to be used when writing a PFX. After loading a PFX, this property is set to the encryption algorithm used by the loaded PFX. (This is the algorithm used for the "shrouded key bag", which is internal to the PFX.)

The default value (for backward compatibility) is "pbeWithSHAAnd3_KeyTripleDES_CBC". Can be set to "pbes2", in which case the Pbes2CryptAlg and Pbes2HmacAlg properies will be set to the algorithms to be used when writing, or the algorithms used by the loaded PFX.

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

• A timeout property set to 0, indicating an infinite timeout.
• A hang occurring within an event callback in the application code.
• An internal bug in the Chilkat code causing the hang.

This property is mainly used in SQL Server stored procedures to retrieve binary data from the last method call that returned binary data. It is only accessible if Chilkat.Global.KeepBinaryResult is set to 1. This feature allows for the retrieval of large varbinary results in an SQL Server environment, which has restrictions on returning large data via method calls, though temp tables can handle binary properties.

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

Indicates the success or failure of the most recent method call: 1 means success, 0 means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.

In SQL Server stored procedures, this property holds the string return value of the most recent method call that returns a string. It is accessible only when Chilkat.Global.KeepStringResult is set to TRUE. SQL Server has limitations on string lengths returned from methods and properties, but temp tables can be used to access large strings.

The length, in characters, of the string contained in the LastStringResult property.

The number of certificates contained in the PFX.

The number of private keys contained in the PFX.

If the AlgorithmId property equals "pbes2", then this is the encryption algorithm to be used when writing the PFX, or used by the PFX that was loaded. If the AlgorithmId is not equal to "pbes2", then the value of this property is meaningless.

Possible values are:

• aes256-cbc
• aes192-cbc
• aes128-cbc
• 3des-cbc

The default value (for writing) is "aes256-cbc". Note: The algorithm specified by this property is only used when the Algorithmid = "pbes2".

If the AlgorithmId property equals "pbes2", then this is the HMAC hash algorithm to be used when writing the PFX, or used by the PFX that was loaded. If the AlgorithmId is not equal to "pbes2", then the value of this property is meaningless.

Possible values are:

• hmacWithSha256
• hmacWithSha384
• hmacWithSha512
• hmacWithSha1

The default value (for writing) is "hmacWithSha256". Note: The algorithm specified by this property is only used when the Algorithmid = "pbes2".

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string and should typically remain empty.

Can be set to a list of the following comma separated keywords:

• "LegacyOrder" - Introduced in v9.5.0.83. Write the internal ContentInfos in the order Chilkat traditionally used in previous versions.
• "NoTruncatePfxPassword64" - Introduced in v9.5.0.87. Microsoft systems/tools such as certmgr.msc would typically truncate extremely long passwords to 64 bytes/chars. Other systems did not. Chilkat will by default truncate passwords to 64 chars. Add this keyword to prevent truncation.

If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

Version of the component/library, such as "10.1.0"

Adds a certificate, its private key (if it exists), and potentially its certificate chain to the PFX. If includeChain is 1, then the certificate must have a private key. The certificate's private key is automatically obtained (internally) via the cert's ExportPrivateKey method. If the certificate's chain of authentication is to be added, it is automatically constructed and added using whatever resources are at hand (such as certs provided via the UseCertVault method, the trusted roots from Chilkat's TrustedRoots class, etc. If a certificate chain is to be added, which is the typical case, then the chain must be completed to the root to succeed.

Returns 1 for success, 0 for failure.

Adds a private key and certificate chain to the PFX. The private key should be such that it is associated with the 1st certificate in the chain. In other words, the 1st certificate in the chain has a public key (embedded within the X.509 structure of the cert itself) that is the counterpart to the private key.

Returns 1 for success, 0 for failure.

Finds and returns the certificate (in the PFX) that has a cert bag "localKeyId" attribute with the specified value. The localKeyId is specifid using the encoding (such as "decimal", "base64", "hex") specified by encoding.

Returns Nothing on failure

Returns the Nth certificate in the PFX. (The 1st certificate is at index 0.)

Returns Nothing on failure

Returns the Nth private key in the PFX. (The 1st private key is at index 0.)

Returns Nothing on failure

Can be called to get one of the following safebag attributes for the Nth private key or certificate in the PFX. forPrivateKey should be 1 for a private key, and 0 for a certificate. The index is the index of the certificate or key in the PFX. The attrName can be one of the following:

• "localKeyId" : Returns the decimal representation of the local key ID. The local key ID is used to associate the certificate contained in the PFX with this private key. (The certificate will include a "localKeyId" attribute in its cert bag of attributes within the PFX.)
• "keyContainerName" : Returns the key container name (or key name) of the private key. For more information about the directories where the Windows OS stores private keys, see https://docs.microsoft.com/en-us/windows/win32/seccng/key-storage-and-retrieval
• "storageProvider" : Returns the name of the Cryptographic Storage Provider to be used for the key.

Note: It is not required that any of the above attributes are present in the PFX.

Returns Nothing on failure

Imports the certificates and private keys contained in the PFX to the MacOS/iOS keychain.

Returns 1 for success, 0 for failure.

Imports the certificates and private keys contained in the PFX to Windows certificate store(s).

If exportable is 1, imported keys are marked as exportable.

If userProtected is 1, the user is to be notified through a dialog box or other method when certain attempts to use this key are made. The precise behavior is specified by the cryptographic service provider (CSP) being used.

If machineKeyset is 1, the private keys are stored under the local computer and not under the current user.

If allowOverwriteKey is 1, allow overwrite of the existing key. Specify this flag when you encounter a scenario in which you must import a PFX file that contains a key name that already exists. For example, when you import a PFX file, it is possible that a container of the same name is already present because there is no unique namespace for key containers. If you have created a "TestKey" on your computer, and then you import a PFX file that also has "TestKey" as the key container, this flag allows the key to be overwritten.

if allowExport is 1, then the key is marked as exportable, which allows for it to be re-exported to a PFX.

The leafStore, intermediateStore, and rootStore are the Windows certificate store names indicating where to import certificates of each given type. A leafStore is a certificate that is not the issuer of any other certificate in the PFX. An intermediateStore is any certificate that is not a root (or self-signed) but is also the issuer of some other certificate in the PFX. A rootStore is a self-signed or root certificate.

The possible store names for leafStore, intermediateStore, and rootStore are as follows:

• "None": Do not import certificates of the given type into any Windows certicate store.
• "AddressBook": Certificate store for other users.
• "AuthRoot": Certificate store for third-party certification authorities (CAs).
• "CertificationAuthority": Certificate store for intermediate certification authorities (CAs).
• "My": Certificate store for personal certificates. (Leaf certificates are typically imported into this store.)
• "Root": Certificate store for trusted root certification authorities (CAs).
• "TrustedPeople": Certificate store for directly trusted people and resources.
• "TrustedPublisher": Certificate store for directly trusted publishers.

The rootStore is reserved for any future options that may be needed. At this time, pass an empty string.

Returns 1 for success, 0 for failure.

Provides information about what transpired in the last method called.

Returns Nothing on failure

Loads a PFX from a PEM formatted string. The PEM can contain the private key, the certificate, and certificates in the chain of authentication up to the CA root. For example:

 -----BEGIN RSA PRIVATE KEY-----
...
... the private key associated with the main certificate.
...
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
... the main certificate
...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
...
... an intermediate CA certificate (if present)
...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
...
... the root CA certificate
...
-----END CERTIFICATE----- 

Returns 1 for success, 0 for failure.

Loads a PFX from in-memory bytes.

If the .pfx/.p12 uses different passwords for integrity and private keys, then the password argument may contain JSON to specify the passwords. See the LoadPfxFile method (below) for details.

Returns 1 for success, 0 for failure.

Loads a PFX from encoded byte data. The encoding can by any encoding, such as "Base64", "modBase64", "Base32", "UU", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", "Q", "B", "url_oath", "url_rfc1738", "url_rfc2396", and "url_rfc3986".

If the .pfx/.p12 uses different passwords for integrity and private keys, then the encoding argument may contain JSON to specify the passwords. See the LoadPfxFile method (below) for details.

Returns 1 for success, 0 for failure.

Loads a PFX from a file.

Starting in v9.5.0.75, a .pfx/.p12 file with different passwords for integrity and private keys can be loaded by passing the following JSON for the password.

    {
      "integrity": "password1",
      "privKeys": "password2",
     }

    {
      "integrity": "password1",
      "privKeys": "not used",
       "skipPrivateKeys": true
     }

Returns 1 for success, 0 for failure.

Sets a safe bag attribute for the Nth private key or certificate in the PFX. Safe bag attributes can be added by calling this method once for each attribute to be added to each certificate or key. forPrivateKey should be 1 for a private key, and 0 for a certificate. The index is the index of the certificate or key in the PFX. (The 1st item is at index 0.) See the example below for more information. The encoding indicates a binary encoding such as "base64", "hex", "decimal", "fingerprint", etc if the value contains binary (non-text) data.

A safe bag attribute can be removed by passing an empty string for the value.

Returns 1 for success, 0 for failure.

Write the PFX to in-memory bytes.

Returns a zero-length byte array (as a Variant) on failure.
An empty array will have a UBound of -1 meaning 0 elements.

Write the PFX to an encoded string. The encoding can be any encoding such as "base64" or "hex".

Returns Nothing on failure

Write the PFX to a file. PFX and PKCS12 are essentially the same. Standard filename extensions are ".pfx" or ".p12".

Returns 1 for success, 0 for failure.

Converts the PFX (PKCS12) to a JavaKeyStore object. One JKS entry per private key found in the PKCS12 is added. The certs found within the PCKS12 are used to build the certificate chains for each private key. (A typical PFX file contains a single private key along with its associated certificate, and the certificates in the chain of authentication to the root CA cert.)

The specified alias is applied to the 1st private key found. If the alias is empty, then the alias is obtained from the cert/PFX in the following order of preference:

1. Certificate's subject common name
2. Certificate's subject email address
3. Certificate's friendly name found in the PKCS9 attributes of the PKCS12
4. Certificate's serial number

If multiple private keys are found in the PKCS12, then all but the first will automaticallly be assigned aliases using the preference just described.

Returns Nothing on failure

Write the PFX to a PEM formatted string. The resultant PEM will contain the private key, as well as the certs in the chain of authentication (or whatever certs are available in the PFX). For example:

 -----BEGIN RSA PRIVATE KEY-----
...
... the private key associated with the main certificate.
...
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
... the main certificate
...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
...
... an intermediate CA certificate (if present)
...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
...
... the root CA certificate
...
-----END CERTIFICATE----- 

Returns Nothing on failure

Write the PFX to a PEM formatted string. If extendedAttrs is 1, then extended properties (Bag Attributes and Key Attributes) are output. If noKeys is 1, then no private keys are output. If noCerts is 1, then no certificates are output. If noCaCerts is 1, then no CA certs or intermediate CA certs are output. If encryptAlg is not empty, it indicates the encryption algorithm to be used for encrypting the private keys (otherwise the private keys are output unencrypted). The possible choices for the encryptAlg are "des3", "aes128", "aes192", and "aes256". (All encryption algorithm choices use CBC mode.) If the private keys are to be encrypted, then password is the password to be used. Otherwise, password may be left empty. For example:
