## AI interpretation — verify before relying

Scramp implements the SCRAM authentication protocol (SCRAM-SHA-1, SCRAM-SHA-256, SCRAM-SHA-512, and SCRAM-SHA3-512 variants) for both client and server roles in Python applications.

Verdict: Scramp is a well-maintained, actively developed SCRAM authentication library with low install friction, permissive licensing, and no known vulnerabilities. It is suitable for applications needing standards-compliant SCRAM authentication on both client and server sides.
