Hi all, From OpenSSL 1.0 change log:

Make PKCS#8 the default write format for private keys, replacing the traditional format. This form is standardised, more secure and doesn't include an implicit MD5 dependency. [Steve Henson]

However, I need the private key file in the previous, traditional format. Is it possible to convert the pem file from PKCS#8 to the traditional format (using OpenSSL.exe app)?

Thank you very much!

+1  A: 

Succeeded to solve that in that way - the request:

openssl req -configconfigfile.cfg -newkey rsa:2048 -keyout newkey.pem -out newreq.pem 365

Then, I converted it to RSA format:

openssl rsa -in newkey.pem -out newkey.pem

Hope that it will help someone.
