Hash Generator vs UUID Generator
cryptography
Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, or SHA-512 hashes from any text input.
Compute cryptographic hashes of any UTF-8 string using the most common algorithms: MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Output is a lowercase hex or base64 digest. Useful for verifying data integrity, generating checksums, and working with APIs that require signed requests.
Example input:
{
"input": "Hello, World!",
"algorithm": "sha256",
"encoding": "hex"
}generation
UUID Generator
Generate one or more cryptographically random UUID v4 identifiers instantly.
Generate cryptographically random UUID version 4 identifiers (RFC 4122) using the Node.js crypto module. Produces between 1 and 100 UUIDs per request, in standard hyphenated format or compact (no hyphens). Also validates whether a given string is a valid UUID.
Example input:
{
"count": 1,
"format": "hyphenated"
