Empower Your Testing with Essential Certificates
ETT Public Cert
The ETT Public Cert is used for signing Direct messages, allowing you to test your system's ability to validate and trust the ETT as a message sender.
Trust Anchor
The Trust Anchor establishes a trusted relationship between your HISP and the ETT by linking the certificate authority's (CA) certificate to the ETT's HISP certificates
Invalid Trust Anchor
The Invalid Trust Anchor simulates an incorrect association between the CA's certificate and the ETT, enabling you to test your system's handling of invalid trust relationships in negative testing scenarios.
Public Root CA
The ETT Public Root CA is a self-signed certificate that identifies the trusted authority responsible for issuing certificates, allowing you to verify the authenticity of the Trust Anchor and the ETT's HISP certificate.
