Summary

Updated navigation links, reformatted FAQ references, fixed typographical errors, emphasized section headers, and rephrased heading text.

Security assessment

Changes are editorial improvements without addressing vulnerabilities. Updates include link redirects (welcome.html→introduction.html), FAQ reference formatting, apostrophe corrections, and bold formatting for list items. No security vulnerabilities are mentioned or patched.

-_Asymmetric_ encryption uses a pair of keys, a public key for encryption and a private key for decryption. You can share the public key because it isn’t used for decryption, but access to the private key should be highly restricted. Asymmetric encryption is generally regarded to be more secure than symmetric encryption, but it is slower because it uses longer key lengths and requires more complex encryption calculations.
