Glossary of Security Terms: Encryption

Too Long; Didn't Read

Mozilla (stylized as moz://a) is a free software community founded in 1998 by members of Netscape. In cryptography, encryption is the conversion of cleartext into a coded text or ciphertext. A ciphertext is intended to be unreadable by unauthorized readers. The reverse operation, decryption, is mathematically hard to perform. How hard depends on the security of the cryptographic algorithm chosen and evolves with the progress of cryptanalysis. It is performed using a specific algorithm and a secret, called the key.
