Symmetric Encryption

This encryption method makes use of same “secret key” to encipher and decipher the message and it is termed as private key encryption. This type of encryption methods uses mathematical operations so it is efficient needs only minimal processing. Both sender and receiver should possess encryption key. If any copy of key is compromised, an intermediate can decrypt and the read messages which was being sent.

The several methods of symmetric encryption techniques are as follows:

Data Encryption Standard (DES) – It is one of the popular symmetric encryption cryptosystems that uses 64-bit block size of plaintext and 56-bit key. This method is adopted by NIST in the year 1976 as federal standard for encrypting non-classified information.
Triple DES (3DES) – This method is formed to provide security far beyond
DES.
Advanced Encryption Standard (AES) – This technique was developed to replace DES and 3DES both.
