find_cipher()

LLA_CRYPTO_API int find_cipher

(

const char *

name

)

Find a registered cipher by name

Parameters

name	The name of the cipher to look for

Returns

>= 0 if found, -1 if not present

find_cipher_any()

int find_cipher_any	(	const char *	name,
		int	blocklen,
		int	keylen
	)

Find a cipher flexibly. First by name then if not present by block and key size

Parameters

name	The name of the cipher desired
blocklen	The minimum length of the block cipher desired (octets)
keylen	The minimum length of the key size desired (octets)

Returns

>= 0 if found, -1 if not present

find_cipher_id()

int find_cipher_id

(

unsigned char

ID

)

Find a cipher by ID number

Parameters

ID	The ID (not same as index) of the cipher to find

Returns

>= 0 if found, -1 if not present

register_cipher()

LLA_CRYPTO_API int register_cipher

(

const struct ltc_cipher_descriptor *

cipher

)

Register a cipher with the descriptor table

Parameters

cipher

The cipher you wish to register

Returns

value >= 0 if successfully added (or already present), -1 if unsuccessful

unregister_cipher()

LLA_CRYPTO_API int unregister_cipher

(

const struct ltc_cipher_descriptor *

cipher

)

Unregister a cipher from the descriptor table

Parameters

cipher

The cipher descriptor to remove

Returns

CRYPT_OK on success
