ProtOSINT

ProtOSINT is a Python script that offers three sub-modules to investigate Protonmail accounts and ProtonVPN IP addresses. The first sub-module tests the validity of a Protonmail account and provides additional information, such as the public key attached to the email, the date the PGP key was created, and the encryption used. The second sub-module generates multiple email addresses by combining information fields to help find a target's Protonmail account. The third sub-module checks if an IP address is currently affiliated with ProtonVPN. ProtOSINT also provides tips for Protonmail investigations, including the fact that Protonmail is case-insensitive and considers certain symbols as transparent. The script can be used to gather information about a target's email encryption keys, custom domain usage, and more. With its ability to provide detailed information about Protonmail accounts and ProtonVPN IP addresses, ProtOSINT is a valuable tool for OSINT investigations.
