Cryptography Utilities

Sha1 Checksum

Generate SHA1 checksums for data integrity verification and file validation. Available through MCP in Cursor and other AI editors, or via REST at `/v1/crypto/checksum/sha1`. Simply provide text or binary data to get the deterministic 40-character hexadecimal hash. Essential for version control systems, file deduplication, and security auditing workflows.

API Endpoint

GET /v1/crypto/checksum/sha1

Code Examples

curl "https://tinyfn.io/v1/crypto/checksum/sha1" \
  -H "X-API-Key: YOUR_API_KEY"

  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/sha1',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

How do I generate a SHA1 hash using MCP in my AI editor?

Call the sha1_checksum tool with your input data. The MCP tool returns the 40-character hex string instantly, perfect for AI agents performing file integrity checks or data validation tasks.

What's the difference between SHA1 and SHA256 checksums?

SHA1 produces 160-bit (40 hex chars) hashes while SHA256 creates 256-bit (64 hex chars) hashes. SHA256 is cryptographically stronger, but SHA1 remains useful for non-security applications like Git commits.

Can I use SHA1 for password hashing or security applications?

No, SHA1 is cryptographically broken for security purposes. Use it only for data integrity, checksums, or legacy compatibility. For passwords, use bcrypt, Argon2, or other secure hashing algorithms.

What input formats does the SHA1 tool accept?

The tool accepts any text string or binary data. Common use cases include hashing file contents, JSON payloads, configuration data, or any string that needs a deterministic identifier.

Why would I use SHA1 instead of MD5 for checksums?

SHA1 is more collision-resistant than MD5 and produces longer hashes (40 vs 32 chars), making accidental duplicates less likely. It's also required by systems like Git for commit identification.
