About this Tool
RSA (Rivest-Shamir-Adleman) is a widely used public-key cryptosystem. It requires a pair of keys: a public key for encryption or signature verification, and a private key for decryption or signature generation. This tool uses server-side cryptographically secure random number generators to create a 2048-bit RSA key pair in PEM format.
Frequently Asked Questions
Are the generated keys stored anywhere?
No. The key pair is generated dynamically in volatile memory and is instantly discarded after being sent to your browser.
Why 2048-bit?
2048-bit RSA keys are the current industry standard, providing an excellent balance between cryptographic security and computational performance.
