Decrypt given data previously encoded with des-ede-ecb cipher algo. Triple DES (DES-EDE) in ECB (Electronic Codebook) mode, applying DES three times with each block encrypted independently. Triple DES, introduced to extend the security of DES, uses ECB mode to encrypt blocks independently, though this comes with vulnerabilities in modern cryptography. While Triple DES improves on DES security, ECB mode introduces pattern leakage in ciphertext, making this combination insecure for most modern applications. 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.
