Method Detail

charsToBytes

public static byte[] charsToBytes(char[] chars)

Converts chars to bytes without using any external functions that might allocate additional buffers for the potentially sensitive data. This guarantees the caller that they only need to cleanup the input and result.

Parameters:

chars - The chars

Returns:

The bytes

bytesToChars

public static char[] bytesToChars(byte[] bytes)

Converts bytes to chars without using any external functions that might allocate additional buffers for the potentially sensitive data. This guarantees the caller that they only need to cleanup the input and result.

Parameters:

bytes - The bytes (to convert into characters).

Returns:

The characters (converted from the specified bytes).

clear

public static void clear(byte[] bytes)

Clears an array of potentially sensitive bytes

Parameters:

bytes - The bytes. May be null.

clear

public static void clear(char[] chars)

Clears an array of potentially sensitive chars

Parameters:

chars - The characters. May be null.

computeBase64SHA1Hash

public static java.lang.String computeBase64SHA1Hash(char[] input)

Computes the base 64 encoded SHA1 hash of the input

Parameters:

input - The input chars

Returns:

the hash

computeBase64SHA1Hash

public static java.lang.String computeBase64SHA1Hash(byte[] bytes)

Computes the base 64 encoded SHA1 hash of the input

Parameters:

bytes - The input bytes.

Returns:

the hash (computed from the input bytes).

verifyBase64SHA1Hash

public static boolean verifyBase64SHA1Hash(char[] input,
                                           java.lang.String hash)

Verifies the base 64-encoded SHA1 hash of the input.

Parameters:

input - The input chars

hash - The expected hash

Returns:

true if the hash of the input characters matches the expected hash.
