+Subject: [PATCH] Fix OpenSSL 4.0 compatibility: replace #peek with accessor
+ functions
+
+ASN1_STRING is opaque in OpenSSL 4.0. Replace direct struct member
+access via #peek with ASN1_STRING_get0_data() and ASN1_STRING_length()
+accessor functions. These accessors have been available since
+OpenSSL 1.1.0 and are compatible with both 3.x and 4.0.
