From 5572f482e797a5f6eee34ef7f04a8defde7bdecf Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Fri, 11 Oct 2002 17:08:27 +0000 Subject: Step 2 of move of engines: copy engines to new directory and rename them to be prefixed with e_ instead of hw_. They aren't necessarely hardware engines. The files commited here are exact copies of the corresponding hw_ files found in crypto/engine/. --- engines/e.ec | 8 + engines/e_4758_cca.c | 967 +++++++++++++++++++++++++++++++++ engines/e_4758_cca_err.c | 149 +++++ engines/e_4758_cca_err.h | 93 ++++ engines/e_aep.c | 1119 ++++++++++++++++++++++++++++++++++++++ engines/e_aep_err.c | 157 ++++++ engines/e_aep_err.h | 101 ++++ engines/e_atalla.c | 592 ++++++++++++++++++++ engines/e_atalla_err.c | 145 +++++ engines/e_atalla_err.h | 89 +++ engines/e_cswift.c | 995 ++++++++++++++++++++++++++++++++++ engines/e_cswift_err.c | 149 +++++ engines/e_cswift_err.h | 93 ++++ engines/e_ncipher.c | 1342 ++++++++++++++++++++++++++++++++++++++++++++++ engines/e_ncipher_err.c | 156 ++++++ engines/e_ncipher_err.h | 100 ++++ engines/e_nuron.c | 416 ++++++++++++++ engines/e_nuron_err.c | 142 +++++ engines/e_nuron_err.h | 86 +++ engines/e_sureware.c | 1040 +++++++++++++++++++++++++++++++++++ engines/e_sureware_err.c | 150 ++++++ engines/e_sureware_err.h | 94 ++++ engines/e_ubsec.c | 1059 ++++++++++++++++++++++++++++++++++++ engines/e_ubsec_err.c | 151 ++++++ engines/e_ubsec_err.h | 95 ++++ 25 files changed, 9488 insertions(+) create mode 100644 engines/e.ec create mode 100644 engines/e_4758_cca.c create mode 100644 engines/e_4758_cca_err.c create mode 100644 engines/e_4758_cca_err.h create mode 100644 engines/e_aep.c create mode 100644 engines/e_aep_err.c create mode 100644 engines/e_aep_err.h create mode 100644 engines/e_atalla.c create mode 100644 engines/e_atalla_err.c create mode 100644 engines/e_atalla_err.h create mode 100644 engines/e_cswift.c create mode 100644 engines/e_cswift_err.c create mode 100644 engines/e_cswift_err.h create mode 100644 engines/e_ncipher.c create mode 100644 engines/e_ncipher_err.c create mode 100644 engines/e_ncipher_err.h create mode 100644 engines/e_nuron.c create mode 100644 engines/e_nuron_err.c create mode 100644 engines/e_nuron_err.h create mode 100644 engines/e_sureware.c create mode 100644 engines/e_sureware_err.c create mode 100644 engines/e_sureware_err.h create mode 100644 engines/e_ubsec.c create mode 100644 engines/e_ubsec_err.c create mode 100644 engines/e_ubsec_err.h (limited to 'engines') diff --git a/engines/e.ec b/engines/e.ec new file mode 100644 index 0000000000..5481a43918 --- /dev/null +++ b/engines/e.ec @@ -0,0 +1,8 @@ +L AEPHK hw_aep_err.h hw_aep_err.c +L ATALLA hw_atalla_err.h hw_atalla_err.c +L CSWIFT hw_cswift_err.h hw_cswift_err.c +L HWCRHK hw_ncipher_err.h hw_ncipher_err.c +L NURON hw_nuron_err.h hw_nuron_err.c +L SUREWARE hw_sureware_err.h hw_sureware_err.c +L UBSEC hw_ubsec_err.h hw_ubsec_err.c +L CCA4758 hw_4758_cca_err.h hw_4758_cca_err.c diff --git a/engines/e_4758_cca.c b/engines/e_4758_cca.c new file mode 100644 index 0000000000..6d41b9ed2a --- /dev/null +++ b/engines/e_4758_cca.c @@ -0,0 +1,967 @@ +/* Author: Maurice Gittens */ +/* ==================================================================== + * Copyright (c) 1999 The OpenSSL Project.
