There are many cryptography techniques that are used to encrypt and decrypt data that are transferred over a network. There are two basic types of cryptography :Symmetric Key and Asymmetric key. This paper describes various encryption techniques(Substitution and transposition) with their limitations ....
Single-key or symmetric-key encryptionalgorithmscreate a fixed length of bits known as ablock cipherwith a secret key that the creator/sender uses to encipher data (encryption) and the receiver uses to decipher it. One example ofsymmetric-key cryptographyis the Advanced Encryption Standard (AES)....
Hash functions.Symmetric and asymmetric cryptographic algorithms both involve transforming plaintext into ciphertext and then back into plaintext. By contrast, a hash function is a one-way encryption algorithm: once you’ve encrypted your plaintext, you can’t ever recover it from the resulting cip...
SAFER is a block chipper that refers to Secure and Fast Encryption Routine. It is a commonly used byte-oriented technique with a 64-bit block capacity. It has very secure decryption and encryption techniques, with ten rounds of which six can be utilized freely. This technology is widely used...
