KeyStore Explorer is a free, open-source Java desktop application that provides a graphical interface replacing the keytool and jarsigner command-line utilities. It manages Java keystores, X.509 certificates, key pairs, CSRs, CRLs, and file/JAR signing across many cryptographic formats.

Use cases

• manage java keystores with a gui instead of keytool
• convert between pkcs12 jks and other keystore formats
• generate rsa ecc or post-quantum key pairs with self-signed certificates
• create and sign certificate signing requests
• sign and verify jar files for code signing
• inspect x509 certificates and crl extensions
• create a simple ca to sign certificates
• import and export private keys in pem pkcs8 or openssl formats

When to choose

• you work with Java keystores, certificates, or code signing and want a GUI instead of command-line tools
• you need to convert keys and certificates between many formats (PKCS#12, JKS, PEM, PVK, OpenSSL, JWK)
• you want to inspect or edit X.509 certificate extensions, CSRs, or CRLs visually
• you need a lightweight CA for signing certificates and CRLs
• you want support for modern algorithms including Ed25519 and post-quantum ML-DSA/ML-KEM/SLH-DSA

When to avoid

• you need fully automated, scriptable certificate management in CI/CD pipelines (CLI tools like keytool or openssl fit better)
• you need a full-featured enterprise CA with revocation infrastructure
• you don't have a Java runtime and can't install one
• you need to manage non-Java secret stores like HashiCorp Vault or cloud KMS
