CryptoTools: Encryption, JWT, Certificates & Forensics for Apple Devices CryptoTools is a privacy-first cryptography and forensic analysis toolkit for Apple devices. Built with SwiftUI, it combines encryption, certificate inspection, ASN.1 parsing, JWT and JWS analysis, JWE support, QR workflows, PKPass tooling, and advanced key utilities in one streamlined app for developers, security professionals, forensic analysts, and technical learners. Designed for transparency and precision, CryptoTools helps you inspect, convert, validate, generate, encrypt, decrypt, and manage sensitive data locally with clear, reproducible results. Features • Encrypt and decrypt data with AES-256-GCM • Generate, import, inspect, and manage cryptographic keys • Parse and analyze ASN.1 structures and certificates • Analyze and verify Apple Sign-In JWTs • Validate and generate JWS in a dedicated UI • Work with JWT, JWS, and JWE flows, including decryption • Use a JWT validator and debugger • Perform SecKey calculations • Generate JWK representations • Export RSA keys to PEM or DER • Manage OpenSSH keys • Generate CSRs • Parse password-protected certificates with OpenSSL • Convert Base64 data quickly and accurately • Share encrypted data through QR codes • Open keys, files, encrypted content, and PKPass workflows via deep links • Access onboarding and in-app technical documentation 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.
