What version of Go are you using (go version)?


Does this issue reproduce with the latest release?


What operating system and processor architecture are you using (go env)?

Any release of Windows supported by Microsoft

What did you do?

Reviewing cryptographic protocols for a downstream project

What did you expect to see?

Use of a modern Windows API to retrieve entropy, namely BCryptGenRandom from CryptoNG, which is compliant with CTR_DRBG from NIST SP800-90.

What did you see instead?

Go calls CryptGenRandom from a deprecated API. The algorithm is not fully documented and is only known in part.
