Does anyone have code snippet for Triple DES algorithm in C ?
Thanks

What Does Triple DES Mean? Triple Data Encryption Standard (DES) is a type of computerized cryptography where block cipher algorithms are applied three times to each data block. The key size is increased in Triple DES to ensure additional security through encryption capabilities. Each block contains 64 bits of data.
Difference between 3DES and DESDES is a symmetric-key algorithm that uses the same key for encryption and decryption processes. 3DES was developed as a more secure alternative because of DES's small key length. 3DES or Triple DES was built upon DES to improve security.
For example, if we take the plaintext message "8787878787878787", and encrypt it with the DES key "0E329232EA6D0D73", we end up with the ciphertext "0000000000000000". If the ciphertext is decrypted with the same secret DES key "0E329232EA6D0D73", the result is the original plaintext "8787878787878787".
OpenSSL is written in C and provides a 3DES algorithm. It may not be as simple as some of the other suggestions, but it may be worth checking out.

Check out the Crypto++ library, they implement tons of algorithms including DES.
