Generate JSON Web Keys (JWK) for RSA, EC (P-256/P-384/P-521/secp256k1), and OKP (Ed25519/Ed448/X25519/X448), or parse an existing JWK to inspect its parameters, thumbprint, and metadata
jwk-generatorSecurity
Decode a JWT (header + payload) with syntax highlighting, diagnose standard claims, and verify the signature with HS*/RS*/PS*/ES*/EdDSA keys — plus a tampered-token forgery demo
jwt-inspector-verifierSecurity
Generate Argon2id password hashes with tunable memory, iterations, parallelism, salt length, and PHC output
argon2-password-hash-generatorSecurity
Encrypt or decrypt portable password-based file bundles with Argon2id, XChaCha20-Poly1305, and optional signatures
age-like-encrypted-file-bundleSecurity
Compare two AGEX bundles and highlight metadata or protection-setting differences
agex-bundle-diffSecurity
Inspect AGEX bundle metadata without decrypting the file contents
agex-bundle-inspectorSecurity
Rewrite exposed AGEX metadata like original filename or signer ID without touching ciphertext bytes
agex-bundle-metadata-redactorSecurity
Re-encrypt an AGEX bundle with a new passphrase and fresh Argon2id/XChaCha parameters
agex-bundle-rewrapperSecurity
Generate an Ed25519 keypair for AGEX bundle signing and verification
agex-keypair-generatorSecurity
Evaluate a passphrase for AGEX file bundles and recommend the most suitable protection profile
agex-passphrase-strength-checkerSecurity
Generate a plain-language share note for an AGEX bundle so recipients know how to decrypt and verify it safely
agex-secure-share-noteSecurity
Verify the Ed25519 signature attached to an AGEX bundle
