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
ctxThe CAMELLIA context to use. This must be initialized and bound to a key.
modeThe mode of operation. This must be either MBEDTLS_CAMELLIA_ENCRYPT or MBEDTLS_CAMELLIA_DECRYPT.
inputThe input block. This must be a readable buffer of size 16 Bytes.
outputThe 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
ctxThe 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
ctxThe 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
ctxThe CAMELLIA context to use. This must be initialized.
keyThe decryption key. This must be a readable buffer of size keybits Bits.
keybitsThe 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
ctxThe CAMELLIA context to use. This must be initialized.
keyThe encryption key to use. This must be a readable buffer of size keybits Bits.
keybitsThe length of key in Bits. This must be either 128, 192 or 256.
Returns
0 if successful.
A negative error code on failure.
