So it may be that the best solution is for your friend to generate a new public-key that he uses for both signing and encrypting. Like I said, because the primary defense against attack is to only sign a cryptographically secure hash of a message, it is not a serious weakness to have such a key.
In order to work with MySQL using Python, you must have some knowledge of SQL

Syntax and content is defined by X.509 v3 standards for digital certificates, defined in IETF specifications. Generate pem encoded private key. Generally when a PEM encoded file is opened in a text editor, it contains very distinct headers and footers.PEM is a widely used encoding format for security certificates. Ssh by pem file to Access ServerIt is a standard procedure, now how to make this work without using password, using just a.pem file?PEMPEM or Privacy Enhanced Mail is a Base64 encoded DER certificate. PEM certificates are frequently used for web servers as they can easily be translated into readable data using a simple text editor. The main file extensions are.pem,.crt,.ca-bundle.A PEM certificate is a base64 (ASCII) encoded block of data encapsulated between -BEGIN CERTIFICATE REQUEST-.
