5.1 Public Interface


5.1.1 Generic functions

Generic Function: accept-security-context (context-or-credentials buffer &key)

For the server to accept a security context from the client.

On the first call to this function, CONTEXT-OR-CREDENTIALS should be a credential object as returned from the initial
call to ACQUIRE-CREDENTIALS. Subsequent calls CONTEXT-OR-CREDENTIALS should be the context returned from the previous call
to this function.

BUFFER is the opaque octet vector sent from the client.

Returns (values context response-buffer continue-needed) where CONTEXT is the context to be used in subsequent calls to this function or other glass functions. RESPONSE-BUFFER is either an opaque octet vector to be sent back to the client, or nil if the context has been completed. CONTINUE-NEEDED is a boolean indicating whether further calls to this function are required before authentication has completed.

May signal GSS-ERROR if authentication fails.

Package

glass.

Source

glass.lisp.

Generic Function: acquire-credentials (mech-type principal &key)

Acquire credentials for the principal named. Returns CREDENTIALS, for input into INITIALIZE-SECURITY-CONTEXT and ACCEPT-SECURITY-CONTEXT. c.f. GSS_Acquire_cred.

MECH-TYPE ::= symbol naming the authentication mechamism.

PRINCIPAL ::= the name of the principal you are requesting credentials for. NIL assumes default.

Returns an opaque credential object to be used in subsequent calls.

Package

glass.

Source

glass.lisp.

Generic Function: context-principal-name (context &key)

Returns a string which represents the name of the principal to which is authenticated by this context. This function should be used by servers wishing to get some information on the identity of the client.

Package

glass.

Source

glass.lisp.

Generic Function: get-mic (context message &key)

Compute a checksum over the message. C.f. GSS_GetMIC.
MESSAGE ::= octet array containing the plaintext.
Returns an octet array.

Package

glass.

Source

glass.lisp.

Generic Function: initialize-security-context (context-or-credentials &key)

Returns a security context to be sent to the application server. c.f. GSS_Init_sec_context.

On the first call CONTEXT-OR-CREDENTIALS should be the result of the initial call to ACQUIRE-CREDENTIALS.

On subsequent calls, CONTEXT-OR-CREDENTIALS should be the context returned from the previous call to INITIALIZE-SECURITY-CONTEXT.

Returns (values context buffer continue-needed) where context is an opaque object to be used in subsequent calls to this or other functions. Buffer is either an opaque octet-vector, which should be sent to the server, or nil if the context has been completed. Continue needed is
a boolean indicating whether further calls to this function need to made before the authentication is complete.

May signal conditions of type GSS-ERROR.

Package

glass.

Source

glass.lisp.

Generic Function: unwrap (context-handle buffer &key)

Decrypt the message. c.f. GSS_Unwrap

BUFFER ::= the wrapped message, as returned by WRAP.
Returns the decrypted plaintext.

Package

glass.

Source

glass.lisp.

Generic Function: verify-mic (context message message-token &key)

Verify the checksum. c.f. GSS_VerifyMIC

MESSAGE ::= octet array containing the original message that was checksum’ed. MESSAGE-TOKEN ::= the checksum, i.e. result of calling GET-MIC.

Returns T if verified.

Package

glass.

Source

glass.lisp.

Generic Function: wrap (context message &key)

Encrypt the message. c.f. GSS_Wrap
MESSAGE ::= octet array containing the plaintext message
Returns an octet array contining the encrypted message.

Package

glass.

Source

glass.lisp.
