Typedef Documentation

mbedtls_camellia_context

typedef struct mbedtls_camellia_context mbedtls_camellia_context

CAMELLIA context structure.

Function Documentation

mbedtls_camellia_crypt_ecb()

int mbedtls_camellia_crypt_ecb	(	mbedtls_camellia_context *	ctx,
		int	mode,
		const unsigned char	input[16],
		unsigned char	output[16]
	)

Perform a CAMELLIA-ECB block encryption/decryption operation.

Parameters

ctx	The CAMELLIA context to use. This must be initialized and bound to a key.
mode	The mode of operation. This must be either MBEDTLS_CAMELLIA_ENCRYPT or MBEDTLS_CAMELLIA_DECRYPT.
input	The input block. This must be a readable buffer of size 16 Bytes.
output	The output block. This must be a writable buffer of size 16 Bytes.

Returns

0 if successful.

A negative error code on failure.

mbedtls_camellia_free()

void mbedtls_camellia_free

(

mbedtls_camellia_context *

ctx

)

Clear a CAMELLIA context.

Parameters

ctx	The CAMELLIA context to be cleared. This may be NULL, in which case this function returns immediately. If it is not NULL, it must be initialized.

mbedtls_camellia_init()

void mbedtls_camellia_init

(

mbedtls_camellia_context *

ctx

)

Initialize a CAMELLIA context.

Parameters

ctx	The CAMELLIA context to be initialized. This must not be NULL.

mbedtls_camellia_setkey_dec()

int mbedtls_camellia_setkey_dec	(	mbedtls_camellia_context *	ctx,
		const unsigned char *	key,
		unsigned int	keybits
	)

Perform a CAMELLIA key schedule operation for decryption.

Parameters

ctx	The CAMELLIA context to use. This must be initialized.
key	The decryption key. This must be a readable buffer of size keybits Bits.
keybits	The length of key in Bits. This must be either 128, 192 or 256.

Returns

0 if successful.

A negative error code on failure.

mbedtls_camellia_setkey_enc()

int mbedtls_camellia_setkey_enc	(	mbedtls_camellia_context *	ctx,
		const unsigned char *	key,
		unsigned int	keybits
	)

Perform a CAMELLIA key schedule operation for encryption.

Parameters

ctx	The CAMELLIA context to use. This must be initialized.
key	The encryption key to use. This must be a readable buffer of size keybits Bits.
keybits	The length of key in Bits. This must be either 128, 192 or 256.

Returns

0 if successful.

A negative error code on failure.
