int blockDecryptCBC (  const blockCipher *  bc, blockCipherParam *  bp, uint32_t *  dst, const uint32_t *  src, unsigned int  nblocks )

This function decrypts a number of data blocks in Cipher Block Chaining mode. Parameters: bc  The blockcipher. bp  The cipher's parameter block. dst  The cleartext data; should be aligned on a 32-bit boundary. src  The ciphertext data; should be aligned on a 32-bit boundary. nblocks  The number of blocks to be decrypted. Return values: 0  on success.
