fix: Croak at load time when system is in FIPS mode#26
Conversation
FIPS 140-2 declares MD5 as insecure. When the system has FIPS mode enabled (/proc/sys/crypto/fips_enabled contains "1"), Digest::MD5 now croaks at load time with a clear error message rather than silently providing a prohibited algorithm. The DIGEST_MD5_FIPS_FILE environment variable allows overriding the path to the FIPS check file, primarily for testing purposes. Fixes #10 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Docker Hub has removed perl:5.8 through perl:5.24 container images, causing CI failures on all branches including main. Replace the container-based approach with shogo82148/actions-setup-perl which builds Perl from source and supports 5.8+. Changes: - Switch linux matrix from Docker containers to actions-setup-perl - Update actions/checkout v2 -> v4 - Update install-with-cpm v1 -> stable (ubuntu job) - Add Perl 5.34, 5.36, 5.38, 5.40 to test matrix - Drop Perl 5.8 (22 years old, minimal practical value) - Add Windows CI job (Strawberry Perl via actions-setup-perl) - Add macOS CI job (system perl, no container) - Limit AUTHOR_TESTING/RELEASE_TESTING to ubuntu job only Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Windows temp paths contain backslashes (C:\Users\...) which get interpreted as Perl escape sequences (\U=uppercase, \f=formfeed) when interpolated into heredoc strings, mangling the FIPS file path. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
When the system has FIPS mode enabled (
/proc/sys/crypto/fips_enabledcontains1),Digest::MD5now croaks at load time with a clear error message. FIPS 140-2 declares MD5 as insecure, and cryptographic libraries are expected to refuse MD5 operations in FIPS mode rather than silently providing a prohibited algorithm.Fixes #10
