Returns an indication of whether the integrity of a message is intact, given its MIC token.


func gss_verify_mic(_ minor_status: UnsafeMutablePointer<OM_uint32>, _ context_handle: gss_ctx_id_t, _ message_buffer: gss_buffer_t, _ token_buffer: gss_buffer_t, _ qop_state: UnsafeMutablePointer<gss_qop_t>?) -> OM_uint32



A pointer to the secondary status result that provides additional information in case of failure.


The context used to send the message.


A buffer holding the message to verify.


A buffer holding the token representing the cryptographic signature the protects the message.


A pointer the function uses to return the quality of protection setting. See Quality of Protection Constants for valid values. Pass NULL to ignore this output.

Return Value

A status code set to GSS_S_COMPLETE if the message is valid, or another value that indicates the reason for failure. See Function Status for a complete enumeration of status outputs.

func gss_wrap(UnsafeMutablePointer<OM_uint32>, gss_ctx_id_t, Int32, gss_qop_t, gss_buffer_t, UnsafeMutablePointer<Int32>?, gss_buffer_t) -> OM_uint32

Returns a secure message created by calculating and attaching a MIC to the input message, and then optionally encrypting it.

func gss_unwrap(UnsafeMutablePointer<OM_uint32>, gss_ctx_id_t, gss_buffer_t, gss_buffer_t, UnsafeMutablePointer<Int32>?, UnsafeMutablePointer<gss_qop_t>?) -> OM_uint32

Returns the original version of a secure message by optionally decrypting it and then extracting and verifying the attached MIC.
