struct FBase64

Class for encoding/decoding Base64 data (RFC 4648)

Type	Name	Description
bool	Decode ( const FString& Source, FString& OutDest, EBase64Mode Mode )	Decodes a Base64 string into a FString
bool	Decode ( const FString& Source, TArray< uint8 >& Dest, EBase64Mode Mode )	Decodes a Base64 string into an array of bytes
bool	Decode ( const CharType* Source, uint32 Length, uint8* Dest, EBase64Mode Mode )	Decodes a Base64 string into a preallocated buffer
FString	Encode ( const FString& Source, EBase64Mode Mode )	Encodes a FString into a Base64 string
FString	Encode ( const TArray< uint8 >& Source, EBase64Mode Mode )	Encodes a binary uint8 array into a Base64 string
FString	Encode ( const uint8* Source, uint32 Length, EBase64Mode Mode )	Encodes the source into a Base64 string
uint32	Encode ( const uint8* Source, uint32 Length, CharType* Dest, EBase64Mode Mode )	Encodes the source into a Base64 string, storing it in a preallocated buffer.
uint32	GetDecodedDataSize ( const FString& Source )	Determine the decoded data size for the incoming base64 encoded string
uint32	GetDecodedDataSize ( const CharType* Source, uint32 Length )	Determine the decoded data size for the incoming base64 encoded string
constexpr uint32	GetEncodedDataSize ( uint32 NumBytes )	Get the encoded data size for the given number of bytes.
constexpr uint32	GetMaxDecodedDataSize ( uint32 NumChars )	Get the maximum decoded data size for the given number of input characters.
