Methods

CreateSeeFile(string, string, bool, long)

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 = 2097152)
Parameters
Type Name Description
string originalFilePath

The file you need to encrypt
string xmlPublicKey

The public key to encrypt the file
bool storeFileIntegrity

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

The bloc size
Returns
Type Description
Task<bool>

IsEncryptionKeyHashMatch(string, string)

Validate if the file was encrypted with the same key

Declaration
public Task<bool> IsEncryptionKeyHashMatch(string filePath, string xmlPublicKey)
Parameters
Type Name Description
string filePath

File's path
string xmlPublicKey

the xml public key that is use to encrypt
Returns
Type Description
Task<bool>

UnEncryptSeeFile(string, string, string, bool, long)

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 = 2097152)
Parameters
Type Name Description
string seeFilePath

see file path
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
string xmlPrivateKey

The xml private key
bool validateFileIntegrity

Do the system need to validate the integrity at the end of the decryption process
long blocSize

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