returns magnet uri if input is base 32 or base 16 encoded sha1 hash, null otherwise

Parameters:

base_hash -

Returns:

getHashFromMagnetURI

public static byte[] getHashFromMagnetURI(String magnetURI)

decodeSHA1Hash

public static byte[] decodeSHA1Hash(String str)

isURL

public static boolean isURL(String sURL)

test string for possibility that it's an URL. Considers 40 byte hex strings as URLs

Parameters:

sURL -

Returns:

isURL

public static boolean isURL(String sURL,
                            boolean bGuess)

parseTextForURL

Like URLEncoder.encode, except translates spaces into %20 instead of +

Parameters:

s -

Returns:

decode

public static String decode(String s)

decodeIfNeeded

public static String decodeIfNeeded(String s)

Unfortunately we have code that mindlessly decoded URLs (FileDownloadWindow) which borked (in the case I discovered) magnet uris with encoded parameters (e.g. the &tr= parameter) - doing so screws stuff up later if, for example, the parameter included an encoded '&'

Parameters:

s -

Returns:
