* Compute MIC in the client when requestedSimo Sorce2014-05-042-4/+24
|
* Add function to verify MICsSimo Sorce2014-05-044-46/+104
|
* Add function to calculate MICSimo Sorce2014-05-042-0/+42
|
* Use target_info parsing helperSimo Sorce2014-05-041-36/+30
| | | | | Target_info can be optional, but it conflicts with channel bindings being requesed.
* Augment target_info processing with a utilitySimo Sorce2014-05-042-0/+91
| | | | | | | | | Thi re-encoded the target_info structure at the client side adding additional provisions of MS-NLMP 3.1.5.2.1 That is: - generate indication that a MIC is requested by the server - add ClientSuppliedTargetName data
* Add internal facility to override standard versionSimo Sorce2014-05-042-8/+31
| | | | This is useufl to use test vetors w/o altering them
* Retry auth with NULL Domain as per specSimo Sorce2014-05-041-23/+37
|
* Remove unnecessary assignmentsSimo Sorce2014-05-041-4/+3
| | | | | | | The calculation was right but some unnecessary assignments were left from a previous version. Also make the length computation more obvious.
* Remove redundant definitionSimo Sorce2014-05-041-17/+4
| | | | | | wire_lm_response is just the same thing as wire_ntlm_response, the only difference is how cli_chal is defined but it is not important from a usage p[oint of view.
* Change input parameter to be constSimo Sorce2014-05-042-2/+2
| | | | It is never and should never be touched so const char * is better.
* Fail if the encryption level is not matchedSimo Sorce2014-05-041-0/+6
| | | | | If the client allows only 128bit security but the server does not offer it, then fail the authentication.
* Do not send LM Response on auth to modern serversSimo Sorce2014-05-042-17/+23
| | | | | | | | | | | If a server send a target_info field in a challenge message it means it does not need nor want a LM Response. See also MS-NLMP 3.1.5.1.2 The authenticate message must alwyas send a lm_chalresp and a nt_chalresp fields in the header but they will be simply zero length, yet the payload pointer must point to the valid payload area. (Windows server fail authentication if the LM Response buffer offset is zero).
* Always use Extedned Session Security when possibleSimo Sorce2014-05-041-0/+1
| | | | | MS-NLMP 3.1.5.1.1 recommends to set the extended session security flag if LM authentication is not going to be used.
* Fix missing assignments in ntlm_decode_target_infoSimo Sorce2014-05-041-2/+4
| | | | | | Missed to see that the server set timestamp and flags. This was preventing MICs from being generated from the client among other things.
* Return flags and time when requestedSimo Sorce2014-05-041-0/+14
| | | | | | | The calling application may want to check what flags were actually negotiated. Spnego also depends on the mechanism properly returning flags when integrity is negotiated for MIC purposes.
* Return Client name if requestedSimo Sorce2014-04-121-0/+9
|
* Fix epoch valueSimo Sorce2014-04-121-1/+1
| | | | It was off by a factor of 10
* Fix segfault in init context.Simo Sorce2014-01-262-6/+11
| | | | | | | | | | | The init context function was improperly initializing the ctx variable (too late) when some early error conditions can happen. Therefore passing to the delete context function a random memory address it would then try to free. This wuld cause a SEGFAULT in most cases. Additionally unfortunately iconv_close() does not follow good practices and blindignly dereferences data, even if the passed in pointer is NULL. So add a check before calling.
* Implement Import/Export cred functionsexport_credSimo Sorce2014-01-123-0/+216
|
* Generalize export_state and related functionsSimo Sorce2014-01-121-75/+82
|
* Expose cred store names in public header file.Simo Sorce2014-01-123-6/+8
| | | | Easier to use from clients this way.
* Implement import context functionSimo Sorce2013-12-151-1/+313
|
* Implement export context functionSimo Sorce2013-12-154-1/+433
| | | | | The Export format version is set to 0.1 Long term keys are not exported.
* Add import/export functions for the RC4 stateSimo Sorce2013-12-152-0/+56
|
* Use RC4 instead of EVP interface of opensslSimo Sorce2013-12-151-49/+10
| | | | | This makes it much easier to export/import the crypto state. In preparation for implemeting import/export of context.
* Fix potential leaks in delete_contextSimo Sorce2013-12-151-0/+6
| | | | | | | | Free RC4 state if any Free workstations tring if any Also make sure to safely zero the struct before freeing to avoid leaking any key material.
* Do not copy creds on the contextSimo Sorce2013-12-152-63/+51
| | | | | There is no need to copy creds around, they are always available or retrievable.
* Fix memleaks in init_sec_contextStefan Becker2013-12-131-1/+3
|
* Fix memory leak with gssntlm_namesSimo Sorce2013-12-131-1/+1
| | | | Thanks to Stefan Becker <chemobejk@gmail.com> for finding this leak.
* Fix NTLM specific cred_store prefixesSimo Sorce2013-11-231-3/+3
| | | | | Can't use ':' in the prefix name as ':' is the separator between prefix and values.
* Add methods to inquire credentialsSimo Sorce2013-10-243-0/+157
| | | | Also add simple sanity check test.
* Add support for NTLMv1 Signing and SealingSimo Sorce2013-10-232-35/+69
| | | | Including tests to verify conformance to MS-NLMP
* Add CRC32 function using Zlib's crc32Simo Sorce2013-10-232-0/+16
|
* Support connectionless signing and sealing.Simo Sorce2013-10-183-11/+104
| | | | | In connectionless mode (GSS_C_DATAGRAM_FLAG on) sealing keys ust be rotated for each message.
* Add way to set sequence numbres.Simo Sorce2013-10-184-0/+77
| | | | | | | | | | | In NTLMSSP connectionless mode applications are supposed to provide the sequence number, however GSSAPI's get_mic and verify_mic functions do not allow to pass an explicit sequence number. Allow to override the context sequence numbers using a custom oid and implemnting gss_set_sec_context_option() Allows the operation only if the context is in connectionless mode.
* Add support for connectionless modeSimo Sorce2013-10-181-46/+117
| | | | | This needs a new GSSAPI flag, for now grab a number and define GSS_C_DATAGRAM_FLAG ourselves.
* Add public devel header fileSimo Sorce2013-10-182-6/+44
| | | | | This contains definitions for various OIDs and flags needed to implemented non-standard features like NTLMSSP Connectionless mode.
* Add special case for enterprise namesSimo Sorce2013-10-181-1/+42
| | | | | | | | | | | | | | | | | | | | | | | | When enterprise names are used they need to be passed with the embedded '@' signed escaped with a '\', when that is done the whole name is used as the user name and the name is not split on the @ or \ characters. These forms are now supported: foo USERNAME: foo DOMAIN: <null> BAR\foo USERNAME: foo DOMAIN: BAR foo@BAR USERNAME: foo DOMAIN: BAR foo\@bar.example.com USERNAME: foo\@bar.example.com DOMAIN: <null>
* Treat NO OID as GSS_C_NT_USER_NAME on importSimo Sorce2013-10-181-3/+6

|
* Fix handling of NULL domainSimo Sorce2013-10-172-10/+17
| | | | | | | | | Fix segafult in NTOWFv2. When domain is NULL it is just omitted from the NTOWFv2 computation. Fix segfault in accept_sec_context, just make dom_name be an empty string. Fix also memory leaks.
* Fix acquiring creds via cred_storeSimo Sorce2013-10-171-0/+26
| | | | Make sure to set the cred type and copy in the name.
