ChangeProtection Method
Changes the protection level of the secret key.
procedure ChangeProtection(OldPassphrase: String; NewPassphrase: String; ProtType: Integer; EncAlgorithm: String; HashAlgorithm: String);
Remarks
Use this method to change the protection level of the Key.
OldPassphrase specifies the current password to decrypt the key, NewPassphrase is the new password for the key, ProtType is the new protection type (see Protection for more details), EncAlgorithm is the key encryption algorithm, and
