Getting encryption state of a string

 


 

To know whether the string is encrypted, use IsECLStringEncrypted function.

 

The following example illustrates how to check whether the string is encrypted and handle wrong password input.

Example:

var

CompStr, DecompStr: string;

begin

{ compress and encrypt a string }

ECLCompressAndEncryptString('test', CompStr, 'Password', ppmFastest);

{ is string encrypted }

if (IsECLStringEncrypted(CompStr)) then

begin

{ try to decompress and decrypt a string with a wrong password}

if (not ECLDecompressAndDecryptString(CompStr, DecompStr, 'Wrong Password')) then

ShowMessage('Decrypting with wrong password is failed!');

{ try to decompress and decrypt a string with right password}

if (not ECLDecompressAndDecryptString(CompStr, DecompStr, 'Password')) then

ShowMessage('Decrypting with right password is failed!');

end

else

{ string is not encrypted, simply decompress a string }

ECLDecompressAndDecryptString(CompStr, DecompStr);

{ show decompressed string }

ShowMessage('Decrypted string: '+DecompStr);

end;
