WebAES is a symmetric cipher which uses the same key for both encryption and decryption process. This symmetric cipher encrypts a 128-bit block of plaintext using a 128-bit key value to produce a 128-bit ciphertext at a time. AES needs a large 128-bit key size to implement encryption and decryption process. AES 128-bit cipher uses 10 rounds (a ...
