QuestionAnswer
3DES Triple Data Encryption Standard - Symmetric encryption algorithm that encrypts data by processing each block of data 3 times using different DES keys each time. 168 bits in length.
HMAC Hash-Based Message Authentication Code - an algorithm that implements a partial digital signature that guarantees the integrity of a message during transmission, but does not provide for nonrepudiation. Uses a secret key with a hashing algorithms.
List 7 Symmetric Key algorithms DES, 3DES, RC4, IDEA, AES, Twofish, Blowfish
RC4 Rivest Cipher 4 - 128bit stream cipher used with SSL, RDP, WEP, WPA, and more. The predictable nature of the key led to the replacement of WEP to WPA
OTP One Time Pad - type of encryption that, when used to the letter is impossible to actually crack without knowing the key (the pad). Each character of plaintext encrypted by a modular addition from a secret key. Oldest form of Cryptography.
Blowfish Symmetric key block cipher that puts 64bit blocks of data through 16 rounds of cryptographic functions using a key length that can vary from 32 to 448bits in size. Alternative to DES. Still used with no successful attack discovered.
TwoFish Works with 128bit blocks of data. block cipher, but the maximum length of the keys used for encryption cant exceed 256bits
PGP Pretty Good Privacy - method of securing emails, created to prevent attackers from intercepting and manipulating email and attachments by encrypting and digitally signing the contents of the email using public key cryptography. Employs DSA, RSA, MD5, SHA
