3DES

In cryptography, Triple DES (3DES), officially the Triple Data Encryption Algorithm (TDEA or Triple DEA), is a symmetric-key block cipher, which applies the DES cipher algorithm three times to each data block.

Blowfish

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.

Sample Entries in Unix/Linux Password Files

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.

Three Types of Cryptography

In this type of cryptography, one key is used to encrypt, and a matching key is used to decrypt. These two keys together are called a key pair. One of these keys is called the secret key or private key, and should be kept secure.

Types of Stream Ciphers

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 Class 3 Certificate

VeriSign uses the concept of classes for different types of digital certificates [3]: 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.
