WebSep 1, 2015 · Normally if someone needs a cryptographically strong random number she won't need a range of [0,27] (which is 5 bit) but something much larger, more like 2048 bits which just does not fit into an int64. So a big.int is returned. Maybe you should generate a long bit sequence and simply base32 encode it? – WebApr 13, 2024 · 1 Answer. The crypto module provides cryptographic functionality that includes a set of wrappers for OpenSSL's hash, HMAC, cipher, decipher, sign, and verify functions. So yes, you'd expect that this is secure, assuming that OpenSSL's random number generator is secure.
