Csp

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.

Returns the name of the currently selected encryption algorithm in the currently selected CSP.

Returns the ID of the currently selected encryption algorithm in the currently selected CSP.

Returns the key-length of the currently selected encryption algorithm in the currently selected CSP.

Returns the name of the currently selected hash algorithm in the currently selected CSP.

Returns the ID of the currently selected hash algorithm in the currently selected CSP.

Returns the bit length of the currently selected hash algorithm in the currently selected CSP.

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 true indicates success, a value of false 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 = true and failure = false.
• 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 true. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

The number of encryption algorithms provided by the currently selected CSP.

The number of hash algorithms provided by the currently selected CSP.

The number of key containers provided by the currently selected CSP.

The number of key exchange algorithms provided by the currently selected CSP.

The number of signature algorithms provided by the currently selected CSP.

The currently selected CSP. To select another CSP, simply set this property to the name of the CSP, such as "Microsoft Enhanced Cryptographic Provider v1.0". If the CSP is not available on your machine, the property value will not change. The initial and default value for this property is "Microsoft Base Cryptographic Provider v1.0".

This is an integer representing the type of CSP. (Chilkat uses it for internal use.)

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

If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. 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"

Returns true if the currently selected CSP contains an encryption algorithm matching the name and key length. Otherwise returns false.

Returns true if the currently selected CSP contains a hash algorithm matching the name and bit length. Otherwise returns false

Selects an encryption algorithm. The return value is the key-length of the algorithm. If the algorithm is not available, the return value is 0. (There usually is not a need to explicitly select the key length, because the key length can be part of the name, such as "AES 128", or it is determined by the CSP. For example, the Microsoft Enhanced CSP will return a 128-bit key length for RC2, whereas the Base CSP will return a 40-bit key length.)

Selects a hash algorithm. The return value is the bit-length of the algorithm. If the algorithm is not available, the return value is 0.
