Method Details

getHash

public static char[] getHash(String algorithm,
 char[] msg)

Generate hash in a hex character representation

Parameters:

algorithm - message digest algorithm

msg - message text

Returns:

hex hash value in text format

Throws:

IllegalArgumentException - if specified algorithm is not supported

See Also:

• for supported algorithms

getSaltedHash

public static char[] getSaltedHash(String algorithm,
 char[] salt,
 char[] msg)

Generate salted hash for specified message. Supplied salt is returned as prefix to returned hash.

Parameters:

algorithm - message digest algorithm

salt - digest salt (use empty string for no salt)

msg - message text

Returns:

salted hash using specified salt which is returned as a prefix to the hash

Throws:

IllegalArgumentException - if specified algorithm is not supported

See Also:

• for supported hash algorithms

getSaltedHash

public static char[] getSaltedHash(String algorithm,
 char[] msg)

Generate salted hash for specified message using random salt. First 4-characters of returned hash correspond to the salt data.

Parameters:

algorithm - message digest algorithm

msg - message text

Returns:

salted hash using randomly generated salt which is returned as a prefix to the hash

Throws:

IllegalArgumentException - if specified algorithm is not supported

See Also:

• for supported hash algorithms

getHash

public static String getHash(String algorithm,
 InputStream in)
                      throws IOException

Generate message digest hash for specified input stream. Stream will be read until EOF is reached.

Parameters:

algorithm - message digest algorithm

in - input stream

Returns:

message digest hash

Throws:

IOException - if reading input stream produces an error

IllegalArgumentException - if specified algorithm is not supported

See Also:

• for supported hash algorithms

getHash

public static String getHash(String algorithm,
 File file)
                      throws IOException

Generate message digest hash for specified file contents.

Parameters:

algorithm - message digest algorithm

file - file to be read

Returns:

message digest hash

Throws:

IOException - if opening or reading file produces an error

IllegalArgumentException - if specified algorithm is not supported

See Also:

• for supported hash algorithms

getHash

public static String getHash(String algorithm,
 List<String> values)

Generate combined message digest hash for all values in the specified values list.

Parameters:

algorithm - message digest algorithm

values - list of text strings

Returns:

message digest hash

Throws:

IllegalArgumentException - if specified algorithm is not supported

See Also:

• for supported hash algorithms

getHash

public static String getHash(String algorithm,
 byte[] values)

Generate combined message digest hash for the bytes in the specified array.

Parameters:

algorithm - message digest algorithm

values - array of bytes to hash

Returns:

message digest hash

Throws:

IllegalArgumentException - if specified algorithm is not supported

See Also:

• for supported hash algorithms

hexDump

public static char[] hexDump(byte[] data)

Convert binary data to a sequence of hex characters.

Parameters:

data - binary data

Returns:

hex character representation of data
