Method Detail

hex

public static String hex(byte[] in)

hex

public static byte[] hex(String s)

base64

public static String base64(byte[] in)

base64

public static byte[] base64(String in)

md5Hex

public static String md5Hex(com.google.common.io.InputSupplier<? extends InputStream> supplier)
                     throws IOException

Throws:

IOException

See Also:

md5(com.google.common.io.InputSupplier), hex(byte[])

md5Base64

public static String md5Base64(com.google.common.io.InputSupplier<? extends InputStream> supplier)
                        throws IOException

Throws:

IOException

See Also:

md5(com.google.common.io.InputSupplier), base64(byte[])

macBase64

public static String macBase64(com.google.common.io.InputSupplier<? extends InputStream> supplier,
                               Mac mac)
                        throws IOException

Computes and returns the MAC value for a supplied input stream. The mac object is reset when this method returns successfully.

Parameters:

supplier - the input stream factory

mac - the mac object

Returns:

the result of Mac.doFinal() after updating the mac object with all of the bytes in the stream and encoding in Base64

Throws:

IOException - if an I/O error occurs

digest

public static byte[] digest(com.google.common.io.InputSupplier<? extends InputStream> supplier,
                            MessageDigest md)
                     throws IOException

Computes and returns the Digest value for a supplied input stream. The digest object is reset when this method returns successfully.

Parameters:

supplier - the input stream factory

md - the digest object

Returns:

the result of MessageDigest.digest() after updating the digest object with all of the bytes in the stream

Throws:

IOException - if an I/O error occurs

md5

public static byte[] md5(com.google.common.io.InputSupplier<? extends InputStream> supplier)
                  throws IOException

Computes and returns the MD5 value for a supplied input stream. A digest object is created and disposed of at runtime, consider using digest(com.google.common.io.InputSupplier, java.security.MessageDigest) to be more efficient.

Parameters:

supplier - the input stream factory

Returns:

the result of MessageDigest.digest() after updating the md5 object with all of the bytes in the stream

Throws:

IOException - if an I/O error occurs

md5

public static byte[] md5(byte[] in)
                  throws IOException

Throws:

IOException

mac

public static byte[] mac(com.google.common.io.InputSupplier<? extends InputStream> supplier,
                         Mac mac)
                  throws IOException

Computes and returns the MAC value for a supplied input stream. The mac object is reset when this method returns successfully.

Parameters:

supplier - the input stream factory

mac - the mac object

Returns:

the result of Mac.doFinal() after updating the mac object with all of the bytes in the stream

Throws:

IOException - if an I/O error occurs

base64Encode

public static String base64Encode(com.google.common.io.InputSupplier<? extends InputStream> supplier)
                           throws IOException

Computes and returns the base64 value for a supplied input stream.

Parameters:

supplier - the input stream factory

Returns:

the result of base 64 encoding all of the bytes in the stream

Throws:

IOException - if an I/O error occurs

base64Decode

public static byte[] base64Decode(com.google.common.io.InputSupplier<? extends InputStream> supplier)
                           throws IOException

Computes and returns the unencoded value for an input stream which is encoded in Base64.

Parameters:

supplier - the input stream factory

Returns:

the result of base 64 decoding all of the bytes in the stream

Throws:

IOException - if an I/O error occurs

hexEncode

public static String hexEncode(com.google.common.io.InputSupplier<? extends InputStream> supplier)
                        throws IOException

Computes and returns the hex value for a supplied input stream.

Parameters:

supplier - the input stream factory

Returns:

the result of hex encoding all of the bytes in the stream

Throws:

IOException - if an I/O error occurs

hexDecode

public static byte[] hexDecode(com.google.common.io.InputSupplier<? extends InputStream> supplier)
                        throws IOException
