Weak ciphers are generally known as encryption/ decryption algorithms that use key sizes that are less than 128 bits (i.e., 16 bytes … 8 bits in a byte) in length. To understand the ramifications of insufficient key length in an encryption scheme, a little background is needed in basic cryptography.
