bouncycastle read private key from file


The key recovery seems to work, and the equals method on the recovered key returns true for the original key, but getAlgorithm() on the original key returns "EC" and on the recovere [user@host secure]~ openssl genrsa -out posvendor.key.pem 2048 [user@host secure]~ openssl rsa -in posvendor.key.pem -pubout -out posvendor.pub.pem writing RSA key [user@host secure]~ ls posvendor.key.pem posvendor.pub.pem .
