-OpenPGP demonstrates significant ["cryptographic agility"](https://en.wikipedia.org/wiki/Cryptographic_agility). It doesn't rely on a single fixed set of algorithms. Instead, it defines a suite of cryptographic primitives from which users (or their applications) can choose.
+OpenPGP incorporates significant ["cryptographic agility"](https://en.wikipedia.org/wiki/Cryptographic_agility). It doesn't rely on a single fixed set of algorithms. Instead, it defines a suite of cryptographic primitives from which users (or their applications) can choose.
 
 This agility facilitates the easy adoption of new cryptographic primitives into the standard, allowing for a seamless transition. Users can gradually migrate to new cryptographic mechanisms without disruption.
