Openssl Generate Rsa 2048 Key
I'm adding HTTPS support to an embedded Linux device. /a-primary-key-can-be-computer-generated.html. I have tried to generate a self-signed certificate with these steps: openssl req -new cert.csr openssl rsa -in privkey.pem -out key.pem o. RSA is an asymmetric public key algorithm that has been formalized in RFC 3447. It is in widespread use in public key infrastructures (PKI) where certificates (cf. OpenSSL::X509::Certificate) often are issued on the basis of a public/private RSA key pair.

How to generate keys in PEM formatusing the OpenSSL command line tools?
RSA keys
The JOSE standard recommends a minimum RSA key size of 2048 bits.
To generate a 2048-bit RSA private + public key pair for use in RSxxx and PSxxxsignatures:
Elliptic Curve keys
Bitcoin generate public key from private key. To generate an EC key pair the curve designation must be specified. Note thatJOSE ESxxx signatures require P-256, P-384 and P-521 curves (see theircorresponding OpenSSL identifiers below).
Elliptic Curve private + public key pair for use with ES256 signatures:
Elliptic Curve private + public key pair for use with ES384 signatures:

PEM key parsing in Java
The BouncyCastle library provides a simpleutility to parse PEM-encoded keys in Java, to use them for JWS or JWE later.

For Maven you should include the following BouncyCastle dependencies (where1.52 is the latest stable version as of May 2015):
