Quick tips

  • Never share your Private Key. Anyone with the Private Key can decrypt messages meant for you.

How to use this tool

  1. Select your desired key size (2048 or 4096 bits recommended).
  2. Click "Generate Key Pair". Generation may take a few seconds.
  3. Copy your Public and Private PEM keys.

Common questions

Why does 4096-bit take so long?

Generating prime numbers mathematically requires intensive CPU resources. It takes longer but offers stronger security.
