From what I can see at https://developer.mozilla.org/en-US/docs/Web/API/Crypto/getRandomValues https://developer.mozilla.org/en-US/docs/Web/API/Crypto/getR... or https://nodejs.org/api/crypto.html#crypto_crypto_randombytes_size_callback https://nodejs.org/api/crypto.html#crypto_crypto_randombytes... ... neither crypto.getRandomBytes() nor Crypto.getRandomValues() are SEEDABLE. There is no argument I could pass in that would produce the same random sequence for the same seed-value. A reproducible random sequence would be useful in many situations I believe. I understand such a thing is not too difficult to program but it may be difficult to get verifiably good quality randomness out of your own implementation.
