Text Hash Generator

Overview

Hash Text calculates eight different hash values for any input text simultaneously, updating all results in real time as you type. It supports MD5, SHA1, SHA224, SHA256, SHA384, SHA512, SHA3, and RIPEMD160, all computed locally in your browser. Each result line has a one-click copy button.

Same Input, Very Different Outputs

To illustrate the length difference between algorithms, here is hello world hashed in several formats:

MD5:      5eb63bbbe01eeed093cb22bb8f5acdc3     (32 hex chars)
SHA1:     2aae6c69bc0b4ab6db7f39be3e...        (40 hex chars)
SHA256:   b94d27b9934d3e08a52e52d7d...          (64 hex chars)
SHA512:   30d8ac7...                            (128 hex chars)
RIPEMD160:98c615784ccb5fe5936fbc0cbe...        (40 hex chars)

The avalanche effect means even one character difference produces completely unrelated output: hello world and hello World share zero similarity in their SHA256 values.

Which Algorithm to Use

Suitable for security use

  • SHA256 — general default for digital signatures, blockchain, integrity checks
  • SHA512 — higher collision resistance when extra security margin matters
  • SHA3 — built on a different design principle than SHA-2 (Keccak); good for future-facing applications

Non-security use only

  • MD5 — fast file integrity checks, cache keys, non-security unique IDs
  • SHA1 — legacy system compatibility (Git object IDs, older protocols)
  • RIPEMD160 — Bitcoin address generation (used alongside SHA256)

Passwords Are Not Safe with These Algorithms

Hashing a password with MD5 or any SHA variant is not a secure storage strategy. Rainbow table attacks can reverse common passwords in seconds when only a plain hash is stored. Password storage requires a salted, slow hash function designed specifically for that purpose — bcrypt or Argon2 — not the general-purpose algorithms this tool provides.
