 ## Introduction
 
-This is TPM2-Plugin to gererate asymetric key pairs from TPM2.0 module 
-and save them in SoftHSM Token object folder in encryped fasion.
+This is TPM2-Plugin to load asymetric key pairs to TPM2.0 module.
 The private part of keys can only be used for signing when it is loaded in TPM module.
