WebCryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used. WebApr 12, 2024 · One downside is that the ciphertext generated by El Gamal is two times the length of the plaintext. However, it creates a different ciphertext each time the same plaintext is encrypted. 9. Elliptic Curve Cryptography.
