Unicode representation and hashes

Why does an emoji hash differ from its Unicode escape text?

The rendered 🚀 character and the literal characters \uD83D\uDE80 are different text inputs. VetaTool hashes whichever characters are actually present in the editor. This tool is free to use. No account or payment is required.

What you can do here

  • MD5 text digests
  • SHA-1 text digests
  • SHA-256 text digests
  • SHA-512 text digests
  • Exact text byte sensitivity
  • Browser-local hashing

Steps

  1. Determine whether the input contains the actual emoji or backslash escape characters.
  2. Decode escapes only when your data format requires it.
  3. Hash the same representation on both sides.

Escapes are syntax until they are decoded

A source-code or JSON escape can represent a Unicode character after parsing. Before parsing, the backslash, letters, and digits are ordinary text and hash differently from the emoji's UTF-8 bytes.

Emoji vs escape text

The two inputs may represent the same concept in source code, but they are different strings before decoding.

Common questions

Frequently asked questions

Does VetaTool decode Unicode escape text before hashing?

No. The Hash Generator hashes the characters present in the text field.

Does the emoji use UTF-8 for hashing?

CryptoJS hashes the JavaScript string as text, which corresponds to its UTF-8 encoded content for these digest functions.
