Class PEMFileRSAPrivateKeySupplier

java.lang.Object

com.oracle.bmc.http.signing.internal.PEMFileRSAPrivateKeySupplier

All Implemented Interfaces:

KeySupplier<RSAPrivateKey>

public class PEMFileRSAPrivateKeySupplier
extends Object
implements KeySupplier<RSAPrivateKey>

An implementation of KeySupplier that supplies a RSA private key from a PEM file. Supports PKCS#8 (starts with ‘—–BEGIN PRIVATE KEY—–’ tag), PKCS#8 encrypted key (starts with ‘—–BEGIN ENCRYPTED PRIVATE KEY—–’ tag) and PKCS#1 (i.e., starts with ‘—–BEGIN RSA PRIVATE KEY—–’ tag) format.

Example commands that can be used to generate a 2048 bits RSA private key: $ openssl genrsa -out privateKey 2048

$ ssh-keygen -t rsa -b 2048
