## MinIO Docker Tips

### MinIO Custom Access and Secret Keys

To override MinIO's auto-generated keys, you may pass secret and access keys explicitly as environment variables. MinIO server also allows regular strings as access and secret keys.

# MinIO FIPS Builds

MinIO creates FIPS builds using a patched version of the Go compiler (that uses BoringCrypto, from BoringSSL, which is [FIPS 140-2 validated](https://csrc.nist.gov/csrc/media/projects/cryptographic-module-validation-program/documents/security-policies/140sp2964.pdf)) published by the Golang Team [here](https://github.com/golang/go/tree/dev.boringcrypto/misc/boring).
