What RSA Key Pair Generator does
local-first
RSA Key Pair Generator creates public and private RSA keys locally in the browser for signatures, JWT integrations, API examples, and encryption experiments. Choose RSA-PSS, RSASSA-PKCS1-v1_5, or RSA-OAEP, select 2048, 3072, or 4096-bit keys, then export PEM or JWK without sending private keys to a server.
