Revisiting the RC4 / RC4_128 Cipher

The implementation of RC4/RC4_128 in SQL Server does not salt the key and this severely weakens the security of data that is encrypted using the RC4/RC4_128 algorithm. In cryptography, an initialization vector (IV) is a fixed size input to a cryptographic algorithm that is typically required to be random or pseudorandom. Salting of cipher keys… Read more
