56-bit encryption
56 bit encryption indicates that the size of the key used to encrypt the message is 56 bits. 56-bit encryption standard was used in DES and RC5 encryption algorithm. Unfortunately, 56-bit encryption has proved too easy to decipher or crack in practice. Now, 128-bit encryption (in 3DES or TDES) have replaced the 56-bit encryption keys (DES). |
