Decrypt given data previously encoded with camellia-192-ctr cipher algo. Camellia in 192-bit key size with CTR mode, enabling fast, parallelized encryption by using a counter for stream generation. CTR mode, a strong and fast encryption mode, was included in the Camellia family to support high-speed cryptographic applications. Camellia-192-CTR is highly secure, fast, and efficient, often used in performance-sensitive environments. 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.
