Filter: C#  VB.NET  Pascal  C++  PHP  Java  

Changes protection level and/or secret key password.

Declaration

[C#]
    void ChangeProtection(string NewPassphrase, TSBPGPProtectionType PrType, int EncAlgorithm, int HshAlgorithm);

[VB.NET]
    Sub ChangeProtection(ByVal NewPassphrase As String, ByVal PrType As TSBPGPProtectionType, ByVal EncAlgorithm As Integer, ByVal HshAlgorithm As Integer)

[Pascal]
    procedure ChangeProtection(const NewPassphrase : string; PrType : TSBPGPProtectionType; EncAlgorithm : integer = SB_PGP_ALGORITHM_SK_CAST5; HshAlgorithm : TSBPGPHashAlgorithm = SB_PGP_ALGORITHM_MD_SHA1);

[C++]
    void ChangeProtection(const std::string &NewPassphrase, TSBPGPProtectionType PrType, int32_t EncAlgorithm, int32_t HshAlgorithm);

[PHP]
    void ChangeProtection(string $NewPassphrase, integer $PrType, integer $EncAlgorithm, integer $HshAlgorithm)

[Java]
    void changeProtection(String NewPassphrase, TSBPGPProtectionType PrType, int EncAlgorithm, int HshAlgorithm);

Parameters

  • NewPassphrase - new password.
  • ProtectionType - type of the protection.
  • EncAlgorithm - encryption algorithm
  • HshAlgorithm - hash algorithm
  • PrType - ...

Protection type values

[.NET] [Pascal] [C++] Description
ptNone = 0 ptNone _ptNone = 0 Key is not encrypted
ptLow = 1 ptLow ptLow = 1 To get the key from password only password hash is used
ptNormal = 2 ptNormal ptNormal = 2 Hash from password and salt concatenation is used
ptHigh = 3 ptHigh ptHigh = 3 Hash from multiple password and salt concatenation is used

Encryption algorithm values

Definition Value Description
SB_PGP_ALGORITHM_SK_PLAINTEXT 0 (0x00) The data are kept ‘as is’, without any encryption
