Is sent in a request header called X-Device-Sig. To be signed with the device key generated on the device. The API services intended for communication with mobile devices require requests Header will look similar to the following:Īuthorization: TRUSONA : 3. Set this value as the Authorization header on the request. Add base 64 value and token as auth headerįinally, join the server token received from Trusona to the base64 signature with a colon, and add a prefix of Note that the hex string itself should be encoded, not the binary signature. YjFjZDQ0NTQ4NTkzMjM0MGZkMmNkMDMxNzkxNzRhYzUyMDUzYjk2ZTkyNGM5NTczZGE2YWM2ODk4MTcxYzgyNw= When all of the items are joined together, the final string will look similar to the following: Take each of the following request attributes

Get the hex representation of the hash.Īfter the body hash is computed, the string to be signed is built.

Collect the request body into a variable.

Important to make sure the body is used after any processing is applied to it, so it is hashed exactly the JSON document) and generate a hash of the body.

Most of the Trusona API services require the request to include an Authorization header The Trusona API - create devices, register users, trusonafy them. Get keys used to sign device identifier JWTs

Create a binding between a user and an RP identifier, from a scanned TruCode Register an identity document with Trusona Look up a Trusonafication (legacy endpoint) Create a Trusonafication (legacy endpoint) Combine the unsigned thumbprint/nonce with the signature Add base 64 value and token as auth header

Use the HMAC-SHA256 algorithm to generate a signature The official version of the EULA is in English only, but we currently have a Japanese language EULA, a Korean language EULA, and a Chinese language EULA available for reference purposes.
