Method Detail

hash

public static String hash(String value)
                   throws UnsupportedEncodingException

Calculates SHA2 algorithm hash value

Parameters:

value - input to be encrypted

Returns:

hashed value of input

Throws:

UnsupportedEncodingException - error if the character encoding is not supported.

hash

public static String hash(String value,
                          boolean forceHash)
                   throws UnsupportedEncodingException

Calculates SHA2 algorithm hash value

Parameters:

value - input to be encrypted

forceHash - encrypts value if true

Throws:

UnsupportedEncodingException

hashBytes

public static String hashBytes(byte[] value)
                        throws UnsupportedEncodingException

Calculates SHA2 algorithm hash value

Parameters:

value - input to be encrypted

Throws:

UnsupportedEncodingException

hashEquals

public static boolean hashEquals(String hash,
                                 String value)
                          throws UnsupportedEncodingException

Checks if specified value hash is the same as passed in hash. If passed in hash is a plain text String, then it simply compares value and hash.

Parameters:

hash - input being compared to value

value - input checked if it exists in hash

Throws:

UnsupportedEncodingException

isHash

public static boolean isHash(String hash)

Returns true if the passed hash value does represent a valid SHA hash value

Parameters:

hash - input being being checked if it is a valid SHA hash value

encrypt

public static String encrypt(String value)
                      throws Exception

Encrypts simple string value

Parameters:

value - input to be encrypted

Returns:

encrypted value of input

Throws:

Exception

isEncrypted

public static boolean isEncrypted(String value)

Returns true if passed value is encrypted

Parameters:

value - String to be checked if it is currently encrypted

Returns:

true if value is encrypted

decrypt

public static String decrypt(String value)
                      throws Exception

Decrypts simple value

Parameters:

value - decrypts if value is valid SHA hash

Returns:

uncrypted value of input

Throws:

Exception

main

public static void main(String[] argv)
                 throws Exception

main method used to encrypt an input at runtime.

Parameters:

argv - value to encrypt

Throws:

Exception
