Decrypt given data previously encoded with des-ede3-ecb cipher algo. Triple DES (DES-EDE3) in ECB (Electronic Codebook) mode, where each plaintext block is encrypted independently. Triple DES was designed to offer enhanced security over DES, but ECB mode does not prevent repeating patterns in the ciphertext, making it vulnerable. DES-EDE3 in ECB is considered insecure due to the lack of block chaining, and the Triple DES cipher is slower compared to modern algorithms. 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.
