If it works, you know the contents were signed with the private key. and verify against the private key generated by Azure AD token.įor validation, developers can decode JWTs using jwt.ms and verify against 'kid' claim. You can obtain public key by calling the public Azure AD OpenID configuration endpoint: To validate the authenticity of the JWT token’s data is by using Azure AD’s public key to verify the signature. Signature contains the digital signature of the token that was generated by Azure AD’s private key and verify that the token was signed by the sender. The first segment is the Header, the second is the Payload, and the third is the Signature.Įach segment is base64url encoded. Parse the JWT to extract its three components. To Verify the JWT token: Verify that the JWT contains three segments, separated by two period ('.') characters. When your internal application receives an access token, it must validate the signature to prove that the token is authentic. An access token contains claims that you can use Azure Active Directory to identify the granted permissions to your APIs. I understand you are looking to verify the signature of the access token issued by Azure Ad by using public endpoint.
