text-hasher

Compute SHA-256 or MD5 hashes of text strings. Useful for quick integrity checks, deduplication, and content fingerprinting without leaving the terminal.

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:

   bash

   echo -n "your text here" | sha256sum | awk '{print $1}'
   

2. Or MD5:

   bash

   echo -n "your text here" | md5sum | awk '{print $1}'
   

3. Compare two hashes with diff:

   bash

   diff <(echo -n "text A" | sha256sum) <(echo -n "text B" | sha256sum)
   

4. Hash from stdin (pipe-friendly):

   bash

   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.
