From 78404434d055ff86177d7c659358c23f12a27a77 Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Sat, 22 Nov 2003 23:38:41 +0000 Subject: Add support for variable-length session keys in our client code. This means that we now support 'net rpc join' with KRB5 (des based) logins. Now, you need to hack 'net' to do that, but the principal is important... When we add kerberos to 'net rpc', it should be possible to still do user management and the like over RPC. (server-side support to follow shortly) Andrew Bartlett (This used to be commit 9ecf9408d98639186b283f1acf0fac46417547d0) --- source3/libsmb/smbdes.c | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) (limited to 'source3/libsmb/smbdes.c') diff --git a/source3/libsmb/smbdes.c b/source3/libsmb/smbdes.c index cde77f94a3..ae946b4a66 100644 --- a/source3/libsmb/smbdes.c +++ b/source3/libsmb/smbdes.c @@ -397,6 +397,46 @@ void SamOEMhash( unsigned char *data, const unsigned char *key, int val) } } +void SamOEMhashBlob( unsigned char *data, int len, DATA_BLOB *key) +{ + unsigned char s_box[256]; + unsigned char index_i = 0; + unsigned char index_j = 0; + unsigned char j = 0; + int ind; + + for (ind = 0; ind < 256; ind++) + { + s_box[ind] = (unsigned char)ind; + } + + for( ind = 0; ind < 256; ind++) + { + unsigned char tc; + + j += (s_box[ind] + key->data[ind%key->length]); + + tc = s_box[ind]; + s_box[ind] = s_box[j]; + s_box[j] = tc; + } + for( ind = 0; ind < len; ind++) + { + unsigned char tc; + unsigned char t; + + index_i++; + index_j += s_box[index_i]; + + tc = s_box[index_i]; + s_box[index_i] = s_box[index_j]; + s_box[index_j] = tc; + + t = s_box[index_i] + s_box[index_j]; + data[ind] = data[ind] ^ s_box[t]; + } +} + /* Decode a sam password hash into a password.
