VarRSABlindCipherText * VarRSACipherText::blind (  const RSACipherText &  aOther, const CODEX_ASN1::BigNumber &  modulus )  const

Blind a ciphertext. Parameters: aOther  Another (plain) ciphertext modulus  The modulus for the group in which ciphertexts live Returns: A pointer to a new ciphertext which is the product of the current ciphertext and the one passed in.
