 =head1 NAME
 
-EVP_CIPHER-NULL - NULL encryption EVP_CIPHER implementation
+EVP_CIPHER-NULL - The NULL EVP_CIPHER implementation
 
 =head1 DESCRIPTION
 
-This module provides support for NULL encryption using the B<EVP_CIPHER> API.
-It simply copies the data without any encryption.
+Support for a NULL symmetric encryption using the B<EVP_CIPHER> API.
+This is used when the TLS cipher suite is TLS_NULL_WITH_NULL_NULL.
+This does no encryption (just copies the data) and has a mac size of zero.

-The default provider offers the following algorithms:
+The following algorithm is available in the default provider:

 =head2 Parameters
 
-The parameters supported by this implementation are detailed in
-L<EVP_EncryptInit(3)/PARAMETERS>.

-"NULL" algorithm is used when the TLS cipher suite is TLS_NULL_WITH_NULL_NULL.
-This does no encryption (just copies the data) and has a mac size of zero.
-This conforms to RFC 5246 section-6.2.3.1.
+See L<EVP_EncryptInit(3)/Gettable EVP_CIPHER parameters>
 
-"NULL-HMAC-SHA256" and "NULL-HMAC-SHA384" are used when the TLS cipher suite is
-TLS_SHA256_SHA256 and TLS_SHA384_SHA384 respectively.
-This conforms to RFC 9150.
