CkoJws

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.

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: YES means success, NO 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.

The number of signatures contained in this JWS.

Controls whether to use the JWS Compact Serialization or JWS JSON Serialization when creating JWSs. The default value is YES, which is to choose the compact serialization when possible. If multiple signatures exist, or if any unprotected headers exist, then JWS JSON Serialization is used regardless of this property setting.

Controls whether to use the flattened or general JWE JSON Serialization when creating JWSs. The default value is YES, which is to choose the flattened serialization when possible. If multiple signatures exist, then the general (non-flattened) JWS JSON Serialization is used regardless of this property setting.

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 YES, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is NO. 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"

Creates and returns the JWS containing one or more signatures according to the previously set payload, headers, and keys.

Returns nil on failure

Creates and returns the JWS by appending it to the contents of sbJws.

Returns YES for success, NO for failure.

Returns the JWS payload. The charset specifies the byte representation to be used in interpreting the bytes of the payload. (For example, "utf-8", "windows-1252", "utf-16", etc.)

Returns nil on failure

Returns the JWS payload by appending it to the binData.

Returns YES for success, NO for failure.

Returns the JWS payload by appending it to the sbPayload. The charset specifies the byte representation to be used in interpreting the bytes of the payload. (For example, "utf-8", "windows-1252", "utf-16", etc.)

Returns YES for success, NO for failure.

Returns the protected header for the Nth signature. The index is the index of the signature. The 1st signature is at index 0. In most cases, a JWS contains a single signature at index 0.

Returns nil on failure

Returns the optional unprotected header for the Nth signature. The index is the index of the signature. The 1st signature is at index 0. In most cases, a JWS contains a single signature at index 0.

Returns nil on failure

Loads a JWS contained in jwsStr.

Returns YES for success, NO for failure.

Loads a JWS from the contents of sbJws.

Returns YES for success, NO for failure.

Sets the MAC key to be used for creating or validating a signature for the algorithms "HS256", "HS384", or "HS512". The key is an encoded string representation of the MAC key bytes. The encoding is an encoding, such as "base64url", "base64", "hex", etc. The 1st signature is at index 0. (Most JWSs only contain a single signature.)

Returns YES for success, NO for failure.

Sets the MAC key to be used for creating or validating a signature for the algorithms "HS256", "HS384", or "HS512". The key contains the binary bytes of the MAC key for the Nth signature. The 1st signature is at index 0.

Returns YES for success, NO for failure.

Sets the JWS payload from the contents of payload. The charset specifies the byte representation to be used for the string that is to be the payload. (For example, "utf-8", "windows-1252", "utf-16", etc.). If includeBom is YES, then the byte-order-mark (BOM), also known as preamble, if one exists for the given charset, is included in the payload. Normally, includeBom should be set to NO.

Returns YES for success, NO for failure.

Sets the JWS payload from the contents of binData.

Returns YES for success, NO for failure.

Sets the JWS payload from the contents of sbPayload. The charset specifies the byte representation to be used for the string that is to be the payload. (For example, "utf-8", "windows-1252", "utf-16", etc.). If includeBom is YES, then the byte-order-mark (BOM), also known as preamble, if one exists for the given charset, is included in the payload. Normally, includeBom should be set to NO.

Returns YES for success, NO for failure.

Sets the private key (ECC or RSA) to be used in creating a signature for the following algorithms:

RS256
RS384
RS512
ES256
ES384
ES512
PS256

Returns YES for success, NO for failure.

Sets a signature's protected header. The index is the index of the signature. The 1st signature is at index 0. In most cases, a JWS contains a single signature at index 0.

Returns YES for success, NO for failure.

Sets a signature's optional unprotected header. The index is the index of the signature. The 1st signature is at index 0. In most cases, a JWS contains a single signature at index 0.

Returns YES for success, NO for failure.

Validates the Nth signature or MAC using the Nth public key or MAC key.

Returns 1 if the signature was validated, thus verifying that the signer used the same MAC key or the matching private key.
Returns 0 if the incorrect public key or MAC key was provided.
Returns -1 for any other error, such as if no public key or MAC key was previously set for the given index.

Prior to calling this method, a program should provide the public key or MAC key via the SetPublicKey, SetMacKey, or SetMacKeyBd methods.
