What

Sensitive-path checks now strip editor and backup suffixes and re-test the underlying name, so a swap file or backup copy of a credential is protected the same way the original is.

Details
  • Suffixes stripped: .sw[a-p], .un~, .rej, .save, .tmp, .bak, .orig, plus #file# and .#file forms.
  • Matches credential directories .ssh, .aws, .azure, .gnupg, .kube, .docker; key extensions pem, key, p12, pfx, keystore, jks; ssh key names; and secrets.yaml/.json/.toml.
  • Names ending in example, sample, template or dist are excused.
  • A group of git and home environment variables is read together, and lookalike characters are folded before matching.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
