Variable Documentation

int(* ast_check_signature)(struct ast_key *key, const char *msg, const char *sig)
 

Initial value:

   stub_ast_check_signature
Check the authenticity of a message signature using a given public key.

Parameters:
key a public key to use to verify
msg the message that has been signed
sig the proposed valid signature in mime64-like encoding
Returns 0 if the signature is valid, or -1 otherwise

int(* ast_check_signature_bin)(struct ast_key *key, const char *msg, int msglen, const unsigned char *sig)
 

Initial value:

   stub_ast_check_signature_bin
Check the authenticity of a message signature using a given public key.

Parameters:
key a public key to use to verify
msg the message that has been signed
sig the proposed valid signature in raw binary representation
Returns 0 if the signature is valid, or -1 otherwise
