Variable Documentation

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

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 Definition at line 51 of file crypto.h.

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

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 Definition at line 61 of file crypto.h.

int(* ast_decrypt_bin)(unsigned char *dst, const unsigned char *src, int srclen, struct ast_key *key)

Parameters: key  a private key to use to decrypt src  the message to decrypt srclen  the length of the message to decrypt dst  a pointer to a buffer of at least srclen bytes in which the decrypted answer will be stored Returns length of decrypted data on success or -1 on failure. Definition at line 107 of file crypto.h.

int(* ast_encrypt_bin)(unsigned char *dst, const unsigned char *src, int srclen, struct ast_key *key)

Parameters: key  a private key to use to encrypt src  the message to encrypt srclen  the length of the message to encrypt dst  a pointer to a buffer of at least srclen * 1.5 bytes in which the encrypted answer will be stored Returns length of encrypted data on success or -1 on failure. Definition at line 95 of file crypto.h.

struct ast_key*(* ast_key_get)(const char *key, int type)

Retrieve a key. Parameters: name  of the key we are retrieving int  type of key (AST_KEY_PUBLIC or AST_KEY_PRIVATE) Returns the key on success or NULL on failure Definition at line 41 of file crypto.h.

int(* ast_sign)(struct ast_key *key, char *msg, char *sig)

Parameters: key  a private key to use to create the signature msg  the message to sign sig  a pointer to a buffer of at least 256 bytes in which the mime64-like encoded signature will be stored Returns 0 on success or -1 on failure. Definition at line 72 of file crypto.h.

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

Parameters: key  a private key to use to create the signature msg  the message to sign sig  a pointer to a buffer of at least 128 bytes in which the raw encoded signature will be stored Returns 0 on success or -1 on failure. Definition at line 83 of file crypto.h.
