PKCS#1 ↔ PKCS#8 Converter | JavaInUse Security Tools

Convert between PKCS#1 and PKCS#8 without guessing flags

Upload a PEM private key, pick the direction, and let the platform call openssl with strict/best-practice defaults so you always get a clean AES-256 protected artifact (or an intentionally unencrypted file when compatibility demands it).
