I am trying to make a web service call with a client certificate I get an error could not establish secure SSL/TLS channel I have checked the client certificate credentials, permissions. All are fine.

In the log for schannel I see this

  1. first schannel log is

CSP Name: Microsoft Strong Cryptographic Provider

CSP Type: 1 Key Name: xxxxx Key Type: unknown Key Flags: 0x20

  1. second schannel log is this fatal error

schannel fatal alert 80. The internal error state is 301.

  1. Third schannel log is

An SSL Client handshake completed successfully. the negotiated cryptographic parameters are as follows Protocol: TLS 1.0 Ciphersuite: 0x2f Exchange Strength: 2048

So this fatal error is breaking my logic. I don't understand why its being thrown when the SSL handshake is then completed successfully.

Please help!!!!

Thanks

  • also this Key Type: unknown looks very suspect – user1173894 Apr 21 '15 at 16:58
  • We ran an SSLDiag utility and believe there may be an issue with the "Key Container" and the "Unique container name" for the imported client certificate The "Unique container name" is missing altogether. The "Key Container" has this single {GUID} whereas it should be something like {uniqueguid}_{machineguid}. This is really odd and we are not sure where or how to fix this for the certificate. Any help or pointers are appreciated. Thanks – user1173894 Apr 23 '15 at 20:41
