PGP Systems and TrueCrypt

PGP is a security software package that supports strong symmetric and public-key encryption and decryption for privacy, confidentiality and authentication of data and network communication, with digital signatures based originally on a web of trust certificates. Its services include key management, entity authentication, and digital signatures. The package incorporates the best modern cryptographic algorithms and protocols. TrueCrypt is today one of the best commonly available applications used to protect data from being read by unauthorized persons. The system secures the data by encrypting it using one of three algorithms: AES, Serpent, and Twofish, or even a combination of them. It is a powerful encryption tool, which gives its users lots of options in the field of data security.
