dear

this command line 

ls_Base64Str = lnv_CoderObject.Base64Encode(Blob(ls_hexvalues , EncodingANSI!))

is not working correctly, so  the ls_hexvalue varible already converted to Blob (binarry vairlable ) by using Blob command inside lnv_codeerobject,base64encode command as the above line, i want encoded base64  without use Blob command, how ?

regards

OK, but each String has some encoding in PowerBuilder.

If you are using a normal PowerBuilder String (UTF16-LE) then you can use the Blob function without any Encoding Enumeration.

That leads to:

ls_Base64Str = lnv_CoderObject.Base64Encode(Blob(ls_yourString))

Maybe my words is not clear, i want encode base64 without using blob, blob is convert the string to binarry/byte , i want encode from string to base64, if there is any way please let me now like another progamming languge (defi or JAVA).

thanks

OK, so you do not trust the blob function. sigh... How about writing that blob into a file and take a look at the hex values?

Or try the crypto API Example from Roland Smith's website.

https://www.topwizprogramming.com/freecode_cryptoapi.html.

This offers an encoding for a string: => of_encode64 (string as_message) returns string

Hi Wagdy Akeela,

at least you need the Blob() function and yes, that will produce a kind of a blob variable and it's space needs to be allocated during the call.

String ls_hexValues
String ls_Base64Str
String ls_hexCheck

ls_hexvalues = "01234567890ABCDEF"

CoderObject lnv_CoderObject
lnv_CoderObject = Create CoderObject

// Encode 
ls_Base64Str = lnv_CoderObject.Base64Encode(Blob(ls_hexvalues , EncodingANSI!))

// .. Decode 
ls_hexCheck = String ( lnv_CoderObject.Base64Decode(ls_Base64Str),  EncodingANSI! )
