From: Nikolaos Chatzikonstantinou Date: Mon, 26 Sep 2022 15:08:18 +0000 (-0400) Subject: Add :pass and :flags to gnutls-boot for :keylist X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=e9983b1b635cbbc5402279dbbe42878902b151db;p=emacs.git Add :pass and :flags to gnutls-boot for :keylist * lisp/net/gnutls.el (gnutls-boot-parameters): Add the keys :pass and :flags, and update the documentation. * src/gnutls.c (gnutls-boot): Add the keys :pass and :flags, and update the documentation. (syms_of_gnutls): Add the symbols :pass, :flags, and the symbols that correspond to the enumeration constants of the GnuTLS enum `gnutls_pkcs_encrypt_flags_t'. (key_file2_aux): Private helper function that translates a list of symbols to its corresponding `unsigned int' value of the GnuTLS C enum `gnutls_pkcs_encrypt_flags_t'.
