-### Public-key cryptography in OpenPGP
+### Usage and terminology in OpenPGP
 
-OpenPGP makes heavy use of public-key cryptography, both for encryption and signing operations.
+OpenPGP extensively uses public-key cryptography for encryption and digital signing operations.
 
 ```{admonition} Terminology
 :class: note
 
-For historical reasons, the OpenPGP RFC and other documentation often use the non-standard term "secret key" instead of the more common "private key."
-
-So in OpenPGP, the pair of terms "public/secret key" is sometimes used instead of the more common "public/private key."
+OpenPGP documentation, including the foundational RFC, opts for the term "secret key" over the more commonly used "private key." As a result, you'll encounter the "public/secret key" pairing more frequently than "public/private key." But don't worry; "secret key" and "private key" serve the same purpose in cryptographic operations. This terminology reflects historical preferences in the OpenPGP community, not a difference in technology.
