Public Key Cryptography

You can message me securely at nathanieljwise@protonmail.com by encrypting your message using OpenSSL and one of my public keys: either RSA or ECC. Send your message and its SHA256 hash to the secure email address above; I'll hash the encrypted message, verify my hash against yours, and decrypt the message.

Each key is also available as an x509 certificate:

• RSA x509
  • Hash: 7c6458f41f184a233ff3f6630a6e6bc9cfbfe78d38283fff066a78815fc69f78
• ECC x509
• Hash: de9eb59b13bc9b5ca4d09cd96a5e2c0f04261b028a360bf3e51fad5ffc552190
