Encrypt given data using des-ede3-cbc cipher algo. Triple DES (DES-EDE3) in CBC (Cipher Block Chaining) mode, where each block is XOR'd with the previous ciphertext block before encryption. CBC mode enhances the security of Triple DES by ensuring that identical blocks of plaintext result in different ciphertexts. Triple DES in CBC is more secure than DES but still slower and less secure than modern alternatives like AES. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
