Prezados,
O ACBr não deve ter dependência da Indy... para realizar o Decode de Base64 por favor utilizem as Units da Synapse...
Unit: synacode.pas
{:Decode string from base64 format.}
function DecodeBase64(const Value: AnsiString): AnsiString;
{:Encodes a string to base64 format.}
function EncodeBase64(const Value: AnsiString): AnsiString;
{:Decode string from modified base64 format. (used in IMAP, for example.)}
function DecodeBase64mod(const Value: AnsiString): AnsiString;
{:Encodes a string to modified base64 format. (used in IMAP, for example.)}
function EncodeBase64mod(const Value: AnsiString): AnsiString;
