SKS OpenPGP Key server VS GPG Suite

The place to publish and search OpenPGP public keys.

Use GPG Suite to encrypt, decrypt, sign and verify files or messages.

Decentralized Network
The SKS OpenPGP Key server is part of a decentralized network, which means it doesn't rely on a single point of failure and can continue to provide services even if parts of the network go down.
Open Source
The software running on SKS Key servers is open source, allowing users to review the code for security flaws or implement improvements, enhancing transparency and trustworthiness.
Interoperability
The SKS Key server network allows for interoperability with other OpenPGP-compliant software and servers, making it easier to share public keys across different systems and users.
Automated Key Synchronization
Keys uploaded to any SKS server are synchronized automatically across the network, ensuring widespread availability and ease of use for those searching for public keys.

Data Inaccuracy
Since anyone can upload keys, the network can contain outdated or inaccurate data, which could result in trust issues if users find and use invalid keys.
Lack of Key Revocation
Once a key is submitted to the SKS server, it's difficult to remove, including revoked keys, which can continue to be distributed and potentially misused.
Privacy Concerns
The open nature of the server means that uploaded keys and some associated metadata are publicly visible, which can raise privacy concerns for individuals sensitive to exposure.
Limited Metadata Management
The SKS Key server software has limited ability to manage or verify the authenticity of metadata associated with keys, which can impact the trustworthiness of the information provided.

Security
GPG Suite provides strong encryption protocols ensuring high security for emails and files, protecting user data from unauthorized access.
Integration
It seamlessly integrates with Apple's Mail app on macOS, offering users a smooth experience in securing their email communications directly from their preferred email client.
Open Source
Being open source, GPG Suite allows users to inspect the code, which enhances trust and potentially boosts the software's security by allowing independent audits.
Comprehensive Tools
GPG Suite provides a suite of tools, including GPG Mail, GPG Keychain, and more, allowing users to handle encryption, decryption, and key management easily.
User-Friendly
The tool suite offers a user-friendly interface for managing cryptographic keys and encrypting or decrypting data, making it accessible even for less tech-savvy users.

MacOS Limitation
GPG Suite is designed specifically for macOS, limiting its use to Apple users and excluding those on other operating systems like Windows and Linux for its full features.
Complexity for Beginners
Despite its user-friendly tools, new users may find the initial setup and understanding of PGP encryption principles complex and challenging without prior knowledge.
Email Platform Restriction
With its primary functionality tied to Apple's Mail app, users who prefer different email clients may not find the integration as seamless or advantageous.
Cost for Full Features
Some of GPG Suite's features, particularly those related to email encryption, may require a paid subscription for full access, which might be a downside for cost-conscious users.
Occasional Bugs
As with many software programs, users may experience occasional bugs or issues, especially when macOS updates are rolled out, potentially leading to temporary disruptions.
