Overview
A comprehensive tool for certificates: Key Pair Generation, CSR Generation, Public Key Derivation, and Inspection.
A powerful and elegant Chrome extension for handling X.509 certificates and cryptographic keys. **Features** 1. Key Pair Generation Generate cryptographic key pairs instantly using the Web Crypto API. - Algorithms: RSA (2048, 4096 bits), ECDSA (P-256, P-384, P-521), and Ed25519. - Standard Formats: Private keys are exported in PKCS#8 and public keys in SPKI. - Save As: Easily download keys with a standard OS save dialog. 2.

Public Key Derivation Extract the public key component from various sources. - Input Types: Supports Private Keys (PKCS#8/PKCS#1), Certificates, or CSRs. - Auto-Detection: Automatically identifies the input type and algorithm. 4. Certificate/CSR Inspector View detailed information about certificates and signing requests. - Comprehensive View: Shows Serial Number, Subject, Issuer, Validity, and Public Key details. - Extension Decoding: Human-readable decoding for SANs, Basic Constraints, Key Usage, and Extended Key Usage (EKU).
