DESCRIPTION

The functions starting with krb5_c are compat functions with MIT kerberos.

The krb5_enc_data structure holds and encrypted data. There are two public accessable members of krb5_enc_data . enctype that holds the encryption type of the data encrypted and ciphertext that is a that might contain the encrypted data.

krb5_c_block_size returns the blocksize of the encryption type.

krb5_c_decrypt decrypts input and store the data in output. If ivec is NULL the default initialization vector for that encryption type will be used.

krb5_c_encrypt encrypts the plaintext in input and store the ciphertext in output .

krb5_c_encrypt_length returns the length the encrypted data given the plaintext length.

krb5_c_enctype_compare compares to encryption types and returns if they use compatible encryption key types.

krb5_c_make_checksum creates a checksum cksum with the checksum type cksumtype of the data in data . key and usage are used if the checksum is a keyed checksum type. Returns 0 or an error code.

krb5_c_verify_checksum verifies the checksum of data in cksum that was created with key using the key usage usage . verify is set to non-zero if the checksum verifies correctly and zero if not. Returns 0 or an error code.

krb5_c_checksum_length returns the length of the checksum.

krb5_c_set_checksum sets the krb5_checksum structure given type and data . The content of cksum should be freeed with krb5_c_free_checksum_contents .

krb5_c_get_checksum retrieves the components of the krb5_checksum . structure. data should be free with krb5_free_data . If some either of data or checksum is not needed for the application, NULL can be passed in.

krb5_c_valid_enctype returns true if etype is a valid encryption type.

krb5_c_valid_cksumtype returns true if ctype is a valid checksum type.

krb5_c_is_keyed_cksum return true if ctype is a keyed checksum type.

krb5_c_is_coll_proof_cksum returns true if ctype is a collition proof checksum type.
