WebCryptographically secure hashes usually work on bitstrings of arbitrary length and output a fixed length bitstring. The secure part is being collision resistant and preimage resistant, so that you have a practical oneway function, and those are the properties you want for "scrambling".. As fgrieu psted in the comments, one easy way to do this is to utilize an … 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.
