Base64Decoder

Base64Decoder()

Syntax

Result = Base64Decoder(Input$, *OutputBuffer, OutputSize)

Description

Decodes the specified Base64 encoded string.

Parameters

Input$ A string containing the encoded data.

*OutputBuffer The output buffer where the plain data will be copied.

OutputSize The size of the output buffer.

The output buffer can be up to 33% smaller than the input buffer, with a minimum size of 64 bytes. It's recommended to get a slightly larger buffer, like 30% smaller to avoid overflows.

Return value

Returns the length of the decoded data in bytes.

Example

  *Text = UTF8("This is a test string!")
    
  Encoded$ = Base64Encoder(*Text, MemorySize(*Text))
  Debug "Encoded: " + Encoded$
  
  *DecodedBuffer = AllocateMemory(1024)
  Base64Decoder(Encoded$, *DecodedBuffer, 1024)
  Debug "Decoded: " + PeekS(*DecodedBuffer, -1, #PB_UTF8)
