     .PARAMETER IncludeDbMasterKey
-        Exports database master keys from system databases and copies them to the export directory.
-        Critical for environments using Transparent Data Encryption (TDE) or encrypted backups where master keys are required for restoration.
+        When specified, exports database certificates (.cer files) and database master keys (.key files) to the export directory.
+        Certificate private keys (.pvk files) are also exported when -EncryptionPassword is provided.
+        Database master keys require -EncryptionPassword to be specified; if omitted, only certificates are exported.
+        Use -Exclude DbCertificates to suppress certificate export while still exporting master keys.
+
+    .PARAMETER EncryptionPassword
+        Secure password used to encrypt exported certificate private key files (.pvk) and database master key backups (.key).
+        When specified with -IncludeDbMasterKey, enables export of private keys alongside certificates and also backs up database master keys.
+        Required for database master key export; optional for certificate export (without it only .cer files are generated).
+
+    .PARAMETER DecryptionPassword
+        Password required to decrypt the certificate's existing private key before it can be re-encrypted for backup.
+        Use this when certificates were originally created with a password or imported from a password-protected source.
+        Only applies when -IncludeDbMasterKey is specified and DbCertificates is not in -Exclude.
 
     .PARAMETER Exclude
         Skips specific object types from the export to reduce scope or avoid problematic areas.
         Useful when you only need certain components or when specific features cause export issues in your environment.
