(but then, of course, well even paranoids have real enemies)

MD-5* compresses any document → 16 characters (=128 bits/ 8)

SHA-1 → 20 characters (160 bits)

SHA-256 → 32 characters (256 bits)

Since often displayed as 'hexadecimal' or 'base64', may appear longer

*MD-5 is old and no longer used for many crypto applications

append an SHA-1 fingerprint to every encrypted message.

1. Fingerprint any message

note the last few characters of SHA-1 Hex.

2. Encrypt same message*

the appended fingerprint matches the one made in 1.

*Outputs different encrypted text; see Message Learn More

don't append an SHA-1 fingerprint to every encrypted file.

Folks don't want to wait (even fraction of minute) for hashing many files.
