64-bit encryption
64 bit encryption indicates that the size of the key used to encrypt the message is 64 bits. 64-bit encryption standard was used in some early Internet and wireless communication encryption algorithms such as DES and WEP. Unfortunately, 64-bit encryption has proved too easy to decipher or crack in practice. Now, 128-bit encryption (in 3DES or TDES) have replaced the 64-bit encryption keys (DES). |
