AES is available in many different encryption packages, and is the first (and only) publicly accessible cipher approved by the National Security Agency (NSA) for top secret information when used in an NSA approved cryptographic module (see Security of AES, below).
Blowfish is a symmetric-key block cipher, designed in 1993 by Bruce Schneier and included in a large number of cipher suites and encryption products. Blowfish provides a good encryption rate in software and no effective cryptanalysis of it has been found to date.
Advanced Encryption Standard (AES) Encryption for Kerberos 5 . A new edition of the Kerberos V5 specification "The Kerberos Network Authentication Service (V5)" . This version obsoletes RFC 1510, clarifies aspects of the protocol and intended use in a more detailed and clearer explanation.
RSA is an Internet encryption and authentication system that uses an algorithm developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman. RSA is an Internet encryption and authentication system that uses an algorithm developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman.
Password: An x character indicates that encrypted password is stored in /etc/shadow file. Please note that you need to use the passwd command to computes the hash of a password typed at the CLI or to store/update the hash of the password in /etc/shadow file.
Twofish is an encryption algorithm based on an earlier algorithm, Blowfish, and was a finalist for a NIST standard algorithm to replace the DES algorithm.

A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream . In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream.
VeriSign uses the concept of classes for different types of digital certificates : Class 1 for individuals, intended for email. Class 2 for organizations, for which proof of identity is required. Class 3 for servers and software signing, for which independent verification and checking of identity and authority is done by the issuing certificate authority. Class 4 for online business transactions between companies.
