Decrypt given data previously encoded with rc2-64-cbc cipher algo. RC2 with a 64-bit key size in CBC mode, chaining blocks of ciphertext to improve security compared to ECB mode. This mode of RC2 was used for secure encryption in legacy systems but is outdated and insecure by current standards. RC2-64-CBC is not recommended for use due to weaknesses in the RC2 algorithm, even with CBC mode. Our decryption process assumes the IV string is prepended in the encoded string during the encryption process. You can not decrypt and get the correct results if the IV or passphrase mismatch occurs between encryption and decryption process.
