Decrypt given data previously encoded with aes-192-ecb cipher algo. AES with 192-bit key in Electronic Codebook (ECB) mode, where identical plaintext blocks encrypt to identical ciphertext blocks. One of the earliest AES modes but considered insecure due to pattern leakage. Not recommended due to susceptibility to frequency analysis and lack of diffusion. 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.
