Adler32 Checksum

Generates Adler-32 checksums for data integrity verification using a faster alternative to CRC32. Access via MCP in Cursor or Windsurf, or call GET /v1/crypto/adler32 with your data. Returns a 32-bit checksum value commonly used in zlib compression. Adler-32 provides good error detection with significantly better performance than cryptographic hashes.

API Endpoint

GET /v1/crypto/adler32

Code Examples

curl "https://tinyfn.io/v1/crypto/adler32" \
  -H "X-API-Key: YOUR_API_KEY"
const response = await fetch('https://tinyfn.io/v1/crypto/adler32', {
  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/adler32',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

What's the difference between Adler-32 and CRC32 checksums?

Adler-32 is faster but slightly less robust than CRC32. Both detect single-bit errors well, but CRC32 has better burst error detection while Adler-32 offers 3-5x better performance.

How do I calculate Adler-32 checksums with MCP in my AI coding assistant?

Use the adler32 tool in Cursor, Claude Code, or other MCP-enabled editors. Pass your string or file content, and get back the 32-bit checksum value for integrity verification.

Can Adler-32 detect all types of data corruption?

No checksum detects all corruption. Adler-32 reliably catches single-bit flips and most random errors, but sophisticated attacks or specific bit patterns might slip through undetected.

What format does the Adler-32 API return?

Returns the checksum as a 32-bit unsigned integer, typically displayed in hexadecimal format. Same deterministic output as zlib's adler32 implementation.

Is Adler-32 suitable for cryptographic security?

No, Adler-32 is for data integrity only, not security. It's easily reversible and collision-prone. Use SHA-256 or similar cryptographic hashes for security applications.
