A SAML signing certificate is a digital certificate used in Security Assertion Markup Language (SAML) for authentication purposes. It ensures the integrity and authenticity of the SAML assertions (statements about a user's identity) by digitally signing them. This helps in preventing tampering and provides a secure way to trust the identity information being exchanged between an identity provider (IdP) and a service provider (SP).
