Business summary:
Practical Cryptography Crypto Home Ciphers Cryptanalysis Hashes Miscellaneous Resources Home Meet Cryptography A branch of both mathematics and computer science, cryptography is the study and practice of obscuring information Cryptography refers almost exclusively to encryption, the process of converting ordinary information (plaintext) into unintelligible gibberish (i.e., ciphertext). Decryption is the reverse, moving from unintelligible ciphertext to plaintext. A cipher (or cypher) is a pair of algorithms which creates the encryption and the reversing decryption.
