FileCrypt Application
The FileCrypt application enables files to be encrypted for a given recipient and then decrypted by that recipient. Since the encrypted file contains a MAC, the recipient of a document will also be able to verify that the encrypted file was not tampered with.
These encrypted files will be stored in this custom format:
| Field | Length (bytes) |
|---|---|
| KeyLength | 4 |
| KeyBytes | As specified by KeyLength |
| AlgParamsLength | 4 |
| AlgParams | As specified by AlgParamsLength |
| MacLength | 4 |
| Mac | As specified by MacLength |
| Encrypted Data | Remainder of file |
