The primary use cases for this software include safeguarding confidential information during transmission, ensuring compliance with regulatory standards such as GDPR and HIPAA, and maintaining the integrity and authenticity of communications. Common features often include end-to-end encryption, digital signatures, user authentication, and the ability to manage encryption keys effectively.
