Cryptography

Generate or use key pairs to encrypt messages with a public key and decrypt them with a private key, ideal for reviewing secure exchange flows and integration tests.

Calculate hashes for text or files to compare integrity, reproduce signatures, validate checksums and review results with common algorithms such as SHA, MD5 or BLAKE2.

Paste a JWT token to inspect its header and payload, review claims, verify the signature when you have the key and detect common authentication issues.

Create temporary links to share text or small files with encryption, password, expiration and read limits when you need to send sensitive data.

Review TLS certificates for domains or IPs to see issuer, validity dates, alternative names, algorithms and trust chain data.

Protect messages or text snippets with a shared key, choose the algorithm and get encrypted or decrypted output for testing, secure exchange or technical validation.

Generate WordPress-compatible hashes or verify passwords against existing hashes for audits, controlled migrations and user database reviews.
