Windows RSA key Generation tool OpenSSL

Download Openssl.zip

1. Generate the original RSA private key file Private_key.pem

OpenSSL genrsa-out Private_key.pem 1024

2. Convert the original RSA private key to PKCS8 format

OpenSSL pkcs8-topk8-inform pem-in private_key.pem-outform pem-nocrypt-out Rsa_private_key.pem

3. Generate RSA Public key RSA_PUBLIC_KEY.PEM

OpenSSL rsa-in private_key.pem-pubout-out rsa_public_key.crt

4. Get the hexadecimal public key from the public key RSA_PUBLIC_KEY.PEM (first 16 binary string)

OpenSSL asn1parse-out temp.ans-i-inform Pem<private_key.pem

Final Get file list:

Rsa_private_key.pem

Rsa_public_key.crt

16 binary Public key string for JS-side encryption
