SecureString ActiveX Reference Documentation
SecureString
Current Version: 10.0.0
A string class that stores the characters in memory in 256-bit AES CBC encrypted form. The encryption key will be a randomly-generated key.
Object Creation
Note: For versions of Chilkat < 10.0.0, use "Chilkat_9_5_0.SecureString" instead of "Chilkat.SecureString" For a specific major version, use "Chilkat.SecureString.<major_version>", such as "Chilkat.SecureString.10" for Chilkat v10.*.* See Chilkat ActiveX Object Creation (ASP) set obj = Server.CreateObject("Chilkat.SecureString") (AutoIt) $obj = ObjCreate("Chilkat.SecureString") (Visual Basic 6.0) Dim obj As New ChilkatSecureString (VBScript) set obj = CreateObject("Chilkat.SecureString") (Delphi) obj := TChilkatSecureString.Create(Self); (FoxPro) loObject = CreateObject('Chilkat.SecureString') (PowerBuilder) lole_object = create oleobject li_rc = lole_object.ConnectToNewObject("Chilkat.SecureString") (SQL Server) EXEC @hr = sp_OACreate 'Chilkat.SecureString', @obj OUT (Javascript) var obj = new ActiveXObject("Chilkat.SecureString");
Properties
LastBinaryResult
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).
topLastMethodSuccess
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.
topLastStringResult
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).
LastStringResultLen
The length, in characters, of the string contained in the LastStringResult property.
topMaintainHash
If set to the name of a hash algorithm, then a hash of the current string value is maintained. This allows for the hash to be verified via the VerifyHash method. Possible hash algorithm names are "sha1", "sha256", "sha384", "sha512", "md5", "md2", "ripemd160", "ripemd128","ripemd256", and "ripemd320".
topReadOnly
Can be set to 1 to make this secure string read-only (cannot be modified).
topMethods
Access
Append
Appends a clear-text string to this secure string. The in-memory data will be decrypted, the string will be appended, and then it will be re-encrypted. Can return 0 if the string has been marked as read-only via the ReadOnly property.
Returns 1 for success, 0 for failure.
topAppendSb
Appends a clear-text string contained in a StringBuilder to this secure string. The in-memory data will be decrypted, the string will be appended, and then it will be re-encrypted. Can return 0 if the string has been marked as read-only via the ReadOnly property.
Returns 1 for success, 0 for failure.
topAppendSecure
Appends the contents of a secure string to this secure string. The in-memory data will be decrypted, the secure string will be appended, and then it will be re-encrypted. Can return 0 if this string has been marked as read-only via the ReadOnly property.
topHashVal
Returns the hash value for the current value of this secure string. The encoding specifies the encoding to be used. It can be any of the binary encoding algorithms, such as "base64", "hex", and many more listed at Chilkat Binary Encodings
Returns Nothing on failure
topLoadFile
Loads the contents of a file into this secure string. The current contents of this object are replaced with the new text from the file.
Returns 1 for success, 0 for failure.
topSecStrEquals
Returns 1 if the secStr equals the contents of this secure string.
Returns 1 for success, 0 for failure.
topVerifyHash
Verifies the hashVal against the hash value stored for the current value of this secure string. The MaintainHash property must've previously been set for this secure string to maintain an internal hash. The encoding specifies the encoding of the hashVal. It can be any of the binary encoding algorithms, such as "base64", "hex", and many more listed at Chilkat Binary Encodings
Returns 1 for success, 0 for failure.
