Load a RSA private key in Java (algid parse error, not a sequence)

Question

I\'m trying to load a private RSA key generated with ssl into java, my code is:

Generate the key:

openssl genrsa -out mykey.pem 1024         


        

Answer 1

Alternately you can conver your mykey.pem to DER format and use your existing code. Following is the openssl command to do that

 
openssl pkcs8 -topk8 -inform PEM -outform DER -in mykey.pem -out mykey.der -nocrypt

The new formatted file will look some thing like
