Function Documentation

int ast_check_signature (  struct ast_key *    key, char *    msg, 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

int ast_check_signature_bin (  struct ast_key *    key, char *    msg, int    msglen, 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

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.

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.

struct ast_key* ast_key_get (  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

int ast_key_init (  int    fd )

Initialize keys (that is, retrieve pass codes for all private keys). Parameters: fd  a file descriptor for I/O for passwords

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.

int ast_sign_bin (  struct ast_key *    key, 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.
