Function Documentation

int crypto_cipher_decrypt	(	struct crypto_cipher *	ctx,
		const u8 *	crypt,
		u8 *	plain,
		size_t	len
	)

crypto_cipher_decrypt - Cipher decrypt : Context pointer from crypto_cipher_init() : Ciphertext to decrypt : Resulting plaintext : Length of the cipher text Returns: 0 on success, -1 on failure

This function is only used with internal TLSv1 implementation (CONFIG_TLS=internal). If that is not used, the crypto wrapper does not need to implement this.

Definition at line 179 of file crypto_internal-cipher.c.

void crypto_cipher_deinit

(

struct crypto_cipher *

ctx

)

crypto_cipher_decrypt - Free cipher context : Context pointer from crypto_cipher_init()

This function is only used with internal TLSv1 implementation (CONFIG_TLS=internal). If that is not used, the crypto wrapper does not need to implement this.

		const u8 *	plain,
		u8 *	crypt,

crypto_cipher_encrypt - Cipher encrypt : Context pointer from crypto_cipher_init() : Plaintext to cipher : Resulting ciphertext : Length of the plaintext Returns: 0 on success, -1 on failure

This function is only used with internal TLSv1 implementation (CONFIG_TLS=internal). If that is not used, the crypto wrapper does not need to implement this.

		size_t	key_len
	)			[read]

crypto_cipher_init - Initialize block/stream cipher function : Cipher algorithm : Initialization vector for block ciphers or NULL for stream ciphers : Cipher key : Length of key in bytes Returns: Pointer to cipher context to use with other cipher functions or NULL on failure

This function is only used with internal TLSv1 implementation (CONFIG_TLS=internal). If that is not used, the crypto wrapper does not need to implement this.
