Best way to base64encode a jpeg file ?

[Ralph DiMola]

I can see getting rid of extraneous CRs or LFs but aren’t "+","/" and "=" part of the encoding and corrupt the base 64 data stream? Or am I missing something?

Use `binfile:` here instead of `file:` so the engine doesn’t treat the data as native text and fiddle with it

You need url safe base64 encoding so you need:

local tEncoded
put base64Encode(pData) into tEncoded
replace return with empty in tEncoded
replace "+" with "-" in tEncoded
replace "/" with "_" in tEncoded
replace "=" with empty in tEncoded
