In order to provide a certain level of security in order to assert the identity of a user between the HIS
and the receiving STS, there are certain requirements that need to be fulfilled.
In a standard SAML 2.0 token exchange, the confidence (or “trust”) level is provided by the use of
digital certificates in order to encrypt and/or sign the message so that the information cannot be
easily disseminated or intercepted.
All user context exchanges should be conducted via a HTTP-POST to a specific processing web form
(or service) on the STS. To ensure the security of the transmission, this communication should
always occur over HTTPS.
The STS supports 5 context modes:
- UserContextMode 1 - SHA-256 hash with User-Specific Secret Key
- UserContextMode 2 - SHA-256 hash with System-Specific Secret Key
- UserContextMode 3 - User-Specific PlaintextKey
- UserContextMode 4 - User Windows Credentials
- UserContextMode 5 - Client Certificates
v1.95 has two additional modes planned for implementation; ADFS and SSO tokens.

- 1 What is the right UserContextMode for my STS integration?
- 2 UserContextMode 1 - SHA-256 hash with User-Specific Secret Key
- 3 UserContextMode 2 - SHA-256 hash with System-Specific Secret Key
- 4 UserContextMode 3 - User-Specific PlaintextKey
- 5 UserContextMode 4 - User Windows Credentials
- 6 UserContextMode 5 - Client Certificates
What is the right UserContextMode for my STS integration?
Our experience is that most organizations are split between UserContextMode 2 and 4.
If the HIS/EMR/EHR or legacy application vendor has the ability to generate cryptographic hashes, the UserContextMode 2 is recommended as it makes the integration effort a lot simpler.
For environments where the Windows credentials are available (workstation, RDP/Citrix session, or a SSO client), then UserContextMode 4 is used.

UserContextMode 1 - SHA-256 hash with User-Specific Secret Key
In this mode the source system provides six attributes
- NameID – source system username
- NameQualifier - optional
- UserContextTimeDate - in “YYYY-MM-DD hh-mm-ss” format
- UserContextID - also set to the source system username
- UserContextMode - set to “1”
- UserContextHash - generated using a user-specific secret key
UserContextMode 2 - SHA-256 hash with System-Specific Secret Key
The system-specific key is set in the STS web.config.
In this mode the source system provides six attributes
- NameID – source system username
- NameQualifier - optional
- UserContextTimeDate - in “YYYY-MM-DD hh-mm-ss” format
- UserContextID - also set to the source system username
- UserContextMode - set to “1”
- UserContextHash - generated using a system-specific secret key
UserContextMode 3 - User-Specific PlaintextKey
- NameID – source system username
- NameQualifier - optional
- UserContextTimeDate - in “YYYY-MM-DD hh-mm-ss” format
- UserContextID - also set to the source system username
- UserContextPassword - user specific password that will allow STS to validate the user
- UserContextWorkstation -
UserContextMode 4 - User Windows Credentials
Additional user and security context will be obtained from the Windows credentials
- NameID – source system username
- NameQualifier - optional
- UserContextID - also set to the source system username
UserContextMode 5 - Client Certificates
Additional user and security context will be obtained from the client certificate
- NameID – source system username
- NameQualifier - optional
- UserContextID - also set to the source system username
