About Password Encryption

The encryptor that you use in your Siebel deployment writes encrypted passwords to the siebns.dat file. The passwords are encrypted using the RC4 algorithm with a 56-bit encryption key. If you install the Siebel Strong Encryption Pack, you can increase the encryption key length used to encrypt passwords to 128-bits.

For more information about the Siebel Strong Encryption Pack, see About the Siebel Strong Encryption Pack.

The encryptor generates the encrypted password using an encryption key that is unique to each parameter. The encryption key itself is generated based on repository information.
