+Subject: [PATCH 28/28] Fix ssl DER EOF detection for openssl 3.5.7
+
+In PEM, we need to parse until error and then suppress
+PEM_R_NO_START_LINE, because PEM allows arbitrary leading and trailing
+data. DER, however, does not. Parsing until error and suppressing
+ASN1_R_HEADER_TOO_LONG doesn't quite work because that error also
+covers some cases that should be rejected.
+
+Instead, check BIO_eof early and stop the loop that way.
+
+Backported for OpenSSL 3.5.7 compatibility on Windows (openssl 3.5.7
+returns ASN1_R_NOT_ENOUGH_DATA at DER EOF instead of ASN1_R_HEADER_TOO_LONG).
