OpenPGP features and specs

  • Interoperability
    OpenPGP is an open standard that's widely supported across various platforms and software, making it possible to work with many different clients and systems.
  • Security
    OpenPGP uses strong cryptographic algorithms to provide confidentiality, integrity, and authentication for communications, offering robust protection against data breaches and snooping.
  • Email Encryption
    OpenPGP is particularly well-known for its ability to encrypt emails, which is crucial for maintaining privacy in digital communication.
  • Authentication and Verification
    It provides a mechanism for signing messages, which can authenticate the sender and verify data integrity, reducing the risk of forgery and tampering.
  • Data Portability
    As an open standard, OpenPGP ensures that data encrypted or signed with one application can be decrypted or verified by another supporting application, preventing vendor lock-in.

Possible disadvantages of OpenPGP

  • Complexity
    The setup and usage of OpenPGP can be complex for non-technical users, involving key generation and management, which could lead to misuse or errors.
  • Key Management
    Maintaining and securing private keys can be cumbersome, and losing a private key can make encrypted data irretrievable.
  • Lack of Forward Secrecy
    OpenPGP does not inherently offer forward secrecy, meaning that if a private key is compromised, previous communications encrypted with the corresponding public key could be decrypted.
  • Integration Challenges
    Integrating OpenPGP into existing systems and workflows can be challenging, especially in environments that have not previously supported encryption.
  • User Adoption
    Even though OpenPGP is widely supported, its adoption among general users remains limited, which can lead to difficulties in communicating securely with others who do not use it.

ProtonMail features and specs

  • End-to-End Encryption
    ProtonMail uses robust end-to-end encryption, ensuring that only the sender and the recipient can read the emails. This enhances the security and privacy of your communications.
  • Zero Access to User Data
    ProtonMail does not have access to user data or emails. This means that even ProtonMail cannot read your emails, providing an additional layer of privacy.
  • Swiss Privacy Laws
    Based in Switzerland, ProtonMail benefits from stringent Swiss privacy laws, which are some of the strongest in the world. This offers users greater legal protection against mass surveillance.
  • Open Source
    ProtonMail's encryption algorithms are open source, which means their code can be reviewed and audited by anyone, promoting transparency and trust.
  • User-Friendly Interface
    ProtonMail offers an intuitive and clean user interface, making it easy for users to manage their emails efficiently.

Possible disadvantages of ProtonMail

  • Limited Free Storage
    The free version of ProtonMail offers only 500 MB of storage, which might be insufficient for users who need to store a large number of emails.
  • Paid Plans
    Advanced features and additional storage require a paid subscription, which may be a hassle for users looking for a completely free service.
  • Search Limitations
    Due to end-to-end encryption, the search functionality in ProtonMail is limited compared to other email services, as the search can only be performed on email subjects, not the content.
  • Compatibility Issues
    ProtonMail's encryption might not be fully compatible with other email services, potentially causing issues with sending and receiving encrypted messages.
  • Learning Curve
    New users who are unfamiliar with encryption concepts might find it slightly challenging to understand and use all of ProtonMail’s security features effectively.

The Top 4 ProtonMail Alternatives
While ProtonMail is generally received in a positive light, it isn’t without its flaws. It’s been subjected to DDoS attacks that have made its services inaccessible to some users. ProtonMail is also not well suited to high-volume use and its subject lines are not encrypted. To some, these issues may be trivial and others may wish to see what else may be available to them.
