Methods

CreateSeeFile(String, String, Boolean, Int64)

Create a see file. The see file is encrypted with AES 256 bits keys. The AES 256 bits keys are encrypted with the PKCS of the xml publickey. We recommand a 4096 PKCS keys.

Declaration
public Task<bool> CreateSeeFile(string originalFilePath, string xmlPublicKey, bool storeFileIntegrity = true, long blocSize = 2097152L)
Parameters
Type Name Description
System.String originalFilePath

The file you need to encrypt
System.String xmlPublicKey

The public key to encrypt the file
System.Boolean storeFileIntegrity

Did the system need to store the SHA1512 hash of the file. That will slower the process
System.Int64 blocSize

The bloc size
Returns
Type Description
System.Threading.Tasks.Task<System.Boolean>

UnEncryptSeeFile(String, String, String, Boolean, Int64)

Unencrypt see file. You need the PCKS private key that was used to encrypt the see file

Declaration
public Task<bool> UnEncryptSeeFile(string seeFilePath, string outputDir, string xmlPrivateKey, bool validateFileIntegrity = true, long blocSize = 2097152L)
Parameters
Type Name Description
System.String seeFilePath

see file path
System.String outputDir

The directory where will be saved the file. The file will have the name of the original file. Ex : myFile.zip.see will be myFile.zip
System.String xmlPrivateKey

The xml private key
System.Boolean validateFileIntegrity

Do the system need to validate the integrity at the end of the decryption process
System.Int64 blocSize

The bloc size of the file. To retreived the header. Wrong bloc size will slower the process
Returns
Type Description
System.Threading.Tasks.Task<System.Boolean>
