Generates SHA256 checksums for data integrity verification and file validation. Use via MCP in Cursor or Windsurf, or call GET /v1/crypto/checksum/sha256 directly. Returns deterministic 64-character hex strings — identical input always produces the same hash. Essential for detecting file corruption or changes.
curl "https://tinyfn.io/v1/crypto/checksum/sha256" \
-H "X-API-Key: YOUR_API_KEY"const response = await fetch('https://tinyfn.io/v1/crypto/checksum/sha256', {
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/sha256',
headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)Connect your AI agent (Claude, Cursor, Windsurf, etc.) to TinyFn's cryptography tools:
{
"mcpServers": {
"tinyfn-crypto": {
"url": "https://tinyfn.io/mcp/crypto",
"headers": {
"X-API-Key": "YOUR_API_KEY"
}
}
}
}Send your data to the endpoint and get back a 64-character hex string. Same input always produces identical output — that's the deterministic guarantee.
SHA256 produces 256-bit hashes (64 hex chars) and is cryptographically secure, while MD5 creates 128-bit hashes (32 hex chars) but has known vulnerabilities.
Yes, generate checksums of downloaded files and compare against known good values. Perfect for AI agents that need to validate file integrity before processing.
Hidden metadata, different line endings (CRLF vs LF), or encoding differences change the actual byte content, resulting in different hashes.
Yes, SHA256 remains cryptographically secure with no known practical attacks. It's widely used in Bitcoin, SSL certificates, and security applications.
