Built for Real Security Workflows
CryptoTools is ideal for testing cryptographic flows, validating signed tokens, inspecting certificates, managing key material, analyzing PKI structures, and sharing protected data across apps and devices.
JWT, JWS, JWE & Apple Sign-In
Inspect token structure, review claims, verify signatures, generate signed payloads, and decrypt supported JWE content in a dedicated interface. CryptoTools also supports Apple Sign-In JWT analysis and verification using Apple public keys, making authentication debugging faster and clearer.
Certificate, ASN.1 & PKI Inspection
Explore certificate contents and ASN.1 objects in a readable, structured format designed for debugging, validation, and forensic review. OpenSSL-based parsing also supports password-protected certificate workflows.
Key Management & Interoperability
Generate, organize, inspect, and transform key material with metadata that supports traceability and repeatable testing. CryptoTools includes JWK generation, RSA export to PEM or DER, OpenSSH key management, CSR generation, and SecKey-based operations for compatibility across common security workflows.
QR, Deep Links & PKPass
Use QR tools and deep links to move secure or structured data efficiently between systems and apps. PKPass support extends CryptoTools to Wallet-related inspection and testing scenarios.
Privacy by Design
CryptoTools follows a local-first approach, minimizes unnecessary network activity, and gives users direct visibility into cryptographic operations, certificate inspection, and token analysis.
Whether you are validating Apple Sign-In tokens, auditing certificates, generating CSRs, testing JWS or JWE payloads, handling RSA or OpenSSH keys, inspecting PKPass content, or learning applied cryptography, CryptoTools delivers a focused and expert-grade toolkit for Apple platforms.
