It is about 10% faster than FISH, yet believed to be much stronger.

WebMar 16, 2024 · Stream cipher comes under the category of the symmetric cipher. It encrypts a given plain text to a cipher text using a secret key. It utilizes a key (128/256 bits) and a nonce digit (64-128 bits) to convert the plaintext to ciphertext. Both the key and nonce digit creates a keystream of pseudorandom bits.
