Text Hasher Skill

Quickly hash a text string with SHA-256 or MD5.

When to Use

  • Verify content integrity after a copy/paste or download
  • Generate a fingerprint for deduplication
  • Confirm two pieces of text are identical

Prerequisites

  • sha256sum or md5sum (usually preinstalled on Linux/macOS)

Steps

  1. Hash text inline:
    echo -n "your text here" | sha256sum | awk '{print $1}'
    
  2. Or MD5:
    echo -n "your text here" | md5sum | awk '{print $1}'
    
  3. Compare two hashes with diff:
    diff <(echo -n "text A" | sha256sum) <(echo -n "text B" | sha256sum)
    
  4. Hash from stdin (pipe-friendly):
    cat data.txt | sha256sum | awk '{print $1}'
    

Notes

  • -n on echo prevents a trailing newline from changing the hash.
  • For large files use sha256sum filename directly.
