Symmetric Encrypt & Decrypt
Algorithm
Key
Symmetric encryption is a type of encryption where the same key is used to both encrypt and decrypt information. It is also called single key encryption or secret key encryption. Symmetric encryption is fast and efficient, but it requires a secure way to share the key between the sender and the receiver. Some examples of symmetric encryption algorithms are AES, DES, RC4. Symmetric encryption is widely used for data protection, authentication and digital signatures.

Beaufort Cipher
Beaufort Cipher, is a polyalphabetic substitution cipher that is similar to the Vigenère cipher, except that it enciphers characters in a slightly different manner.
Bifid Cipher
Bifid Cipher is a cipher which combines the Polybius square with transposition, and uses fractionation to achieve diffusion.
Four-Square Cipher
Four-Square Cipher encrypts pairs of letters (like playfair), which makes it significantly stronger than substitution ciphers etc. since frequency analysis becomes much more difficult.
Vernam Cipher
Vernam Cipher (also known as the one-time pad (OTP)) is an encryption technique that cannot be cracked, but requires the use of a one-time pre-shared key the same size as, or longer than, the message being sent.
