Cryptography Utilities

Sha512 Checksum

Generate SHA512 checksums for data integrity verification and file validation. Use via MCP in Cursor or Windsurf, or call GET /v1/crypto/checksum/sha512 directly. Pass text or file content to get a 128-character hexadecimal hash. SHA512 produces 512-bit digests, making it suitable for cryptographic applications requiring strong collision resistance.

API Endpoint

GET /v1/crypto/checksum/sha512

Code Examples

curl "https://tinyfn.io/v1/crypto/checksum/sha512" \
  -H "X-API-Key: YOUR_API_KEY"
const response = await fetch('https://tinyfn.io/v1/crypto/checksum/sha512', {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);
import requests

response = requests.get('https://tinyfn.io/v1/crypto/checksum/sha512',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

How do I generate a SHA512 checksum using MCP in Cursor?

Call the sha512_checksum tool with your input data. The MCP tool accepts text strings and returns a 128-character hexadecimal hash for verification purposes.

What's the difference between SHA256 and SHA512 checksums?

SHA512 produces 512-bit (64-byte) hashes versus SHA256's 256-bit (32-byte) hashes. SHA512 offers stronger security but uses more computational resources and storage space.

Can I verify file integrity by comparing SHA512 checksums?

Yes, identical files produce identical SHA512 hashes. Generate checksums before and after file transfer or storage to detect corruption or tampering.

What format does the SHA512 checksum API return?

Returns a 128-character lowercase hexadecimal string representing the 512-bit hash. Example output: 'cf83e1357eefb8bd...' (truncated for brevity).

Is SHA512 suitable for password hashing?

No, use dedicated password hashing functions like bcrypt or Argon2 instead. SHA512 is designed for checksums and digital signatures, not password storage.
