Function silc_cipher_alloc
SYNOPSIS

        SilcBool silc_cipher_alloc(const unsigned char *name,
                                   SilcCipher *new_cipher);

DESCRIPTION

        Allocates a new SILC cipher object. Function returns 1 on succes and 0
        on error. The allocated cipher is returned in new_cipher argument. The
        caller must set the key to the cipher after this function has returned
        by calling the ciphers set_key function.

        The following ciphers are supported:

        aes-256-ctr            AES-256, Counter mode
        aes-192-ctr            AES-192, Counter mode
        aes-128-ctr            AES,128, Counter mode
        aes-256-cbc            AES-256, Cipher block chaining mode
        aes-192-cbc            AES-192, Cipher block chaining mode
        aes-128-cbc            AES,128, Cipher block chaining mode
        twofish-256-cbc        Twofish-256, Cipher block chaining mode
        twofish-192-cbc        Twofish-192, Cipher block chaining mode
        twofish-128-cbc        Twofish-128, Cipher block chaining mode

        Notes about modes:

        The CTR is normal counter mode.  The CTR mode does not require the
        plaintext length to be multiple by the cipher block size.  If the last
        plaintext block is shorter the remaining bits of the key stream are
        used next time silc_cipher_encrypt is called.  If silc_cipher_set_iv
        is called it will reset the counter for a new block (discarding any
        remaining bits from previous key stream).

        The CBC is mode is a standard CBC mode.  The plaintext length must be
        multiple by the cipher block size.  If it isn't the plaintext must be
        padded.
