The previous article was about decoding of Base64 strings (Base64 decoder). This article contains reverse function - Base64Encode. You can use to convert String data to a Base64 string.
To convert binary data to a Base64 string see conversion functions from binary data to a string. You can do simple function to convert binary data:
function can only work with small amount of data - VBS does
not enable to work with buffers to improve performance. Consumed processor time rapidly
grows with source data length (by square). Please use Base64 property of
ByteArray object (ScriptUtilities library, C++ COM object, comercial) if you want to work
with large data. ByteArray lets you also work with codepage (charset) conversions and provides binary file access and binary-to-string conversion. ScriptUtilities is also available with source code.
Next table contains consumed processor time of this VBS code (Base64Encode) and C++ (Base64) on Duron 700 processor. You can see that VBS function is usable for maximum of 50-100 kB.
