Additional changes: - use EC_GROUP_get_degree() in apps/req.c - add ECDSA and ECDH to apps/speed.c - adds support for EC curves over binary fields to ECDSA - new function EC_KEY_up_ref() in crypto/ec/ec_key.c - reorganize crypto/ecdsa/ecdsatest.c - add engine support for ECDH - fix a few bugs in ECDSA engine support Submitted by: Douglas Stebila --- crypto/ecdh/ecdh.h | 164 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 164 insertions(+) create mode 100644 crypto/ecdh/ecdh.h (limited to 'crypto/ecdh/ecdh.h') diff --git a/crypto/ecdh/ecdh.h b/crypto/ecdh/ecdh.h new file mode 100644 index 0000000000..b5b877b55f --- /dev/null +++ b/crypto/ecdh/ecdh.h @@ -0,0 +1,164 @@ +/* crypto/ecdh/ecdh.h */ +/* ==================================================================== + * Copyright 2002 Sun Microsystems, Inc.
