mmhh. , already there?

https://docs.appeon.com/pb2019/powerscript_reference/ch10s38.html

Example from the Help:

Blob lblb_data
String ls_Base64Str

CoderObject lnv_CoderObject
lnv_CoderObject = Create CoderObject

//ls_Base64Str = lnv_CoderObject.Base64Encode(Blob("Test Base64", EncodingANSI!))
ls_Base64Str = "VGVzdCBCYXNlNjQ="

lblb_data = lnv_CoderObject.Base64Decode(ls_Base64Str)
messagebox("Base64Decode", string(lblb_data, EncodingANSI!))

Hi Arnd,

 

Thanks for sharing the API info for string base64 decryption which helped me.

I have one more query, we are using AES encryption as well. we need a decryption API for AES encrypted string.

I have attached the sample API's we use AES Encryption to encrypt and decrypt strings

Please share the sample application or API details or related links if you have any.

 

Thanks,

Suresh

In PowerBuilder 19 you can use .NET Classes from assemblies.

This way, you can use your EncryptDecrypt.EncryptandDecrypts from a simple DLL.

Is there any need to transform this code to "pure" PowerBuilder Code (aka PowerScript)?



If you want to transform this to PowerBuilder Code, the crypter object is your friend.

https://docs.appeon.com/pb2019r2beta/objects_and_controls/ch02s15.html

Take a look at the SymmetricEncrypt/SymmetricDecrypt functions.

I have used the .Net Com Dll in power builder code and it worked. Thanks for your quick replays :)
