Thanks for the link I am able to encrypt and decrypt a text . While authenticating a user what shoul I do.Comare the ciphertext of the Passwords or decrypt them and compare. I cant compare the ciphertextscos everytime the RSA class uses a random key.So the ciphertext used while storing the passwd may not be the same as while comparing. Secondly when i fetch a value of passwd from the databaseit should be in the Byte[] form so that i can decrypt it.How do i store a Byte value in sql server.
