Pem

When set to 1, each of the Load* methods appends to the current contents of this PEM object. When set to 0, a Load* method replaces the contents of this PEM object. The default is 0.

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
3. there is an internal problem (bug) in the Chilkat code that causes the hang.

This is the number of milliseconds between each AbortCheck event callback. The AbortCheck callback allows an application to abort any event-enabled methods prior to completion. If HeartbeatMs is 0 (the default), no AbortCheck event callbacks will fire.

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to 1. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

Indicate whether the last method call succeeded or failed. A value of 1 indicates success, a value of 0 indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

• Any method that returns a string.
• Any method returning a Chilkat object, binary bytes, or a date/time.
• Any method returning a standard boolean status value where success = 1 and failure = 0.
• Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to 1. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to 1. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).

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

The number of certificates in the loaded PEM. To get the 1st certificate, call GetCert(0).

The number of certificate revocation lists (CRLs) in the loaded PEM.

The number of certificate signing requests (CSRs) in the loaded PEM.

The number of private keys in the loaded PEM. To get the 1st private key, call GetPrivateKey(0).

The number of public keys in the loaded PEM. To get the 1st public key, call GetPublicKey(0).

Controls the format to be used for unencrypted private keys when writing a PEM. Possible values are "pkcs1" and "pkcs8". (OpenSSL typically uses the "pkcs8" format.) When writing encrypted private keys to PEM, the format is always PKCS8, and the PEM header is "BEGIN ENCRYPTED PRIVATE KEY". The default is "pkcs8".

The PKCS1 format uses the PEM header: BEGIN RSA PRIVATE KEY.
The PKCS8 format uses the PEM header: BEGIN PRIVATE KEY.

Controls the format to be used for public keys when writing a PEM. Possible values are "pkcs1" and "pkcs8". (OpenSSL typically uses the "pkcs8" format.) The default is "pkcs8".

The PKCS1 format uses the PEM header: BEGIN RSA PUBLIC KEY.
The PKCS8 format uses the PEM header: BEGIN PUBLIC KEY.

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 "9.5.0.94"

Adds a certificate, and potentially the certs in its chain of authentication to the PEM. If includeChain is 1, then certificates in the cert's chain of authentication up to and including the root are automatically added.

Returns 1 for success, 0 for failure.

Adds a certificate, private key, public key, or csr to the PEM. The possible values for itemType are "certificate" (or "cert"), "privateKey", "publicKey", or "csr". The encoding can be "Base64", "modBase64", "Base32", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", "url_oauth", "url_rfc1738", "url_rfc2396", and "url_rfc3986". The itemData contains the ASN.1 data in string format according to the encoding specified in encoding.

Returns 1 for success, 0 for failure.

Adds a private key to the PEM object.

Returns 1 for success, 0 for failure.

Adds a private key and it's associated certificate chain to the PEM object.

Returns 1 for success, 0 for failure.

Adds a public key to the PEM object.

Returns 1 for success, 0 for failure.

Removes all content from this PEM object.

Returns 1 for success, 0 for failure.

Returns the Nth certificate from the PEM. The first certificate is at index 0.

Returns Nothing on failure

Returns the encoded contents of the Nth item of a particular type (0-based index). The possible values for itemType are "certificate" (or "cert"), "privateKey", "publicKey", or "csr". Input string args are case-insensitive. If the itemType is "privateKey", the itemSubType may be "der" or "pkcs8". If the itemType is "publicKey", the itemSubType may be "der" or "pkcs1". The itemSubType is ignored for other values of itemType. The valid encoding modes are "Base64", "modBase64", "Base32", "Base58", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", "url_oauth", "url_rfc1738", "url_rfc2396", and "url_rfc3986".

Returns Nothing on failure

Loads the PEM from the contents of an in-memory PKCS7 container (.p7b).

Returns 1 for success, 0 for failure.

Creates an asynchronous task to call the LoadP7b method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

Loads the contents of a PKCS7 container (.p7b file).

Returns 1 for success, 0 for failure.

Creates an asynchronous task to call the LoadP7bFile method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns Nothing on failure

Loads the PEM from a PEM string. If encrypted, then the password is required for decryption. Otherwise, an empty string (or any string) may be passed for the password.

Returns 1 for success, 0 for failure.

Creates an asynchronous task to call the LoadPem method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns 1 for success, 0 for failure.

Removes the Nth private key from the PEM. The first private key is at index 0.

Returns 1 for success, 0 for failure.

Converts the PEM to JKS and returns the Java KeyStore object. If the alias is non-empty, the 1st object (private key or certificate) will use the alias, and all others (if any) will receive auto-generated aliases. The JKS returned will be encrypted using the provided password. If the PEM contains only certificates (no private keys), then the password is unused.

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:

Bag Attributes
    Microsoft Local Key set: <No Values>
    localKeyID: 01 00 00 00 
    friendlyName: le-2b09a3d2-9037-4a05-95cc-4d44518e8607
    Microsoft CSP Name: Microsoft RSA SChannel Cryptographic Provider

Returns Nothing on failure

Converts the PEM to PKCS12 and returns the PFX object. The PFX object has method for saving to a file, exporting to an encoded string, converting to a JKS (Java Keystore), or even converting back to PEM.

Note: The PEM must contain at least one private key to convert to PKCS12. The typical case is that a PKCS12 contains a single private key, along with the associated certificate and the certificates in the chain of authentication.

Returns Nothing on failure

Provides the opportunity for a method call to be aborted. The AbortCheck event is fired periodically based on the value of the HeartbeatMs property. If HeartbeatMs is 0, then no AbortCheck events will fire. As an example, to fire 5 AbortCheck events per second, set the HeartbeatMs property equal to 200.

VB6 Event callback implementation:

Important: Event callbacks from asynchronous method calls are generally not possible from the ActiveX. See VB6 Async Callbacks

Dim WithEvents myPem As ChilkatPem

Private Sub myPem_AbortCheck(abort As Long)

	'Insert application code here.

End Sub

Provides the percentage completed for any method that involves network communications or time-consuming processing (assuming it is a method where a percentage completion can be measured). This event is only fired when it is possible to know a percentage completion, and when it makes sense to express the operation as a percentage completed. The pctDone argument will have a value from 1 to 100. For operations (Chilkat method calls) that complete very quickly, the number of PercentDone callbacks will vary, but the final callback should have a value of 100. For long running operations, no more than one callback per percentage point will occur (for example: 1, 2, 3, ... 98, 99, 100).

The PercentDone callback counts as an AbortCheck event. For method calls that complete quickly such that PercentDone events fire, it may be that AbortCheck events don't fire because the opportunity to abort is already provided in the PercentDone callback. For time consuming operations, where the amount of time between PercentDone callbacks are long, AbortCheck callbacks may be used to allow for the operation to be aborted in a more responsive manner.

The abort output argument provides a means for aborting the operation. Setting it to 1 will cause the method to abort and return a failed status (or whatever return value indicates failure).
