RESTAPI:Email based Verification

Using the email based verification, a verification has to be performed for each sender email address. This makes sure that the sender address that is being used for a transfer through the REST API is valid and authorized for use by its owner. That's important, because the Cryptshare Policy set up on the server grants usage permissions and settings based on the email addresses used for a transfer. To verify a specific sender email address, you need to send a verification request for that email address to the Cryptshare Server. The Cryptshare Server will then send a verification email containing a verification code to the specified sender email address. This verification code will then need to be sent to the Cryptshare server via the REST API to prove that the request was authorized by the email address owner. When the verification code is correct, a verification token is assigned to the REST API consumer that now can be used for the different services. This verification token is only valid for the respective email address and client id. We recommend the email based verification approach for all purposes where users want to perform actions for themselves and have access to their own email inbox, especially for web applications.
