For client-side encryption, you have to use two javascript. If you can send the key securely, then there's no point in symmetrically encrypting the data; just send the data using the secure method you used to send the key. Encryption and Decryption The concept of encryption is the process of converting electronic data into another equivalent form, called "ciphertext" that cannot be easily understood by anybody except the authorized personnel. The function returns a binary string. i want to encrypt the password and username in the same page and send the request to server, then decrypt those values.
