* ITFlow - GET/POST request handler for client credentials

|
|
* Every handler checks the credential module and the credential's own client;
|
|
* anything a form names - the asset, the contact, the tags, a vendor to link
|
|
* to - must be that client's. Usernames and passwords are encrypted with the
|
|
* session's vault key (credentialFormSet() in functions/credential.php), and
|
|
* nothing is saved when the vault did not open, rather than writing an empty
|
|
* password over the real one. Vendors and licenses link through post/link.php.
