Decrypt given data previously encoded with camellia-128-ecb cipher algo. Camellia in 128-bit key size with ECB (Electronic Codebook) mode, where each block is encrypted independently. Camellia was developed by Mitsubishi Electric and NTT as an AES alternative and includes ECB as one of its modes. ECB mode is less secure because repeated plaintext blocks result in identical ciphertext blocks. Camellia is secure, but ECB is not recommended for general use. 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.
