From 10fd98a804097002f9331e48fc6f84f3f3d8f3e2 Mon Sep 17 00:00:00 2001 From: Kaz Kylheku Date: Fri, 23 Aug 2019 19:32:15 -0700 Subject: New: MD5 digest functions. * Makefile (OBJS): New object file, chksums/md5.o. * chksum.c (sha256_ensure_buf): Renamed to chksum_ensure_buf and made generic so MD5 code can borrow it. (sha256_stream, sha256): Call chksum_ensure_buf instead of sha256_ensure_buf, passing in new length and hash name parameters. (md5_stream_impl, md5_buf, md5_str): New static functions. (md5_stream, md5): New functions. (chksum_init): Register md5-stream and md5 intrinsics. * chksum.h (md5_stream, md5): Declared. * chksums/md5.c, chksums/md5.h: New files. --- chksums/md5.h | 41 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 chksums/md5.h (limited to 'chksums/md5.h') diff --git a/chksums/md5.h b/chksums/md5.h new file mode 100644 index 00000000..10d28d73 --- /dev/null +++ b/chksums/md5.h @@ -0,0 +1,41 @@ +/* + * RSA Data Security, Inc., MD5 message-digest algorithm + * + * Copyright (C) 1991-2, RSA Data Security, Inc.
