Crypto random bytes
WebGenerates a string of pseudo-random bytes, with the number of bytes determined by the length parameter. It also indicates if a cryptographically strong algorithm was used to produce the pseudo-random bytes, and does this via the optional crypto_strong parameter. It's rare for this to be FALSE, but some systems may be broken or old.

WebAEAD’s typically require a nonce in addition to the key. For the purposes we require symmetric cryptography for, we need encryption to be stateless. Because of this we use random nonces. (Thus the AEAD must support random nonces) We currently construct a random nonce, and encrypt the data with it. The returned value is nonce encrypted data ...
