Method Detail

sha1

public static String sha1(String input)

Hashes the input string with the SHA-1 algorithm and returns the string hex representation.

Parameters:

input - the string that will be hashed

Returns:

the string hex representation of the SHA-1 hash

sha1

public static String sha1(byte[] input)

Hashes the byte array with the SHA-1 algorithm and returns the string hex representation.

Parameters:

input - the byte array that will be hashed

Returns:

the string hex representation of the SHA-1 hash

sha512

public static String sha512(String input)

Hashes the input string with the SHA-512 algorithm and returns the string hex representation.

Parameters:

input - the string that will be hashed

Returns:

the string hex representation of the SHA-512 hash

sha512

public static String sha512(byte[] input)

Hashes the input byte array with the SHA-512 algorithm and returns the string hex representation.

Parameters:

input - the byte array that will be hashed

Returns:

the string hex representation of the SHA-512 hash

hash

public static String hash(String algorithm,
                          byte[] input)
                   throws NoSuchAlgorithmException

Hashes the input byte array using the given algorithm and returns the string hex representation.

Parameters:

algorithm - the hash algorithm (e.g. "SHA-512")

input - the byte array that will be hashed

Returns:

the string hex representation of the hash

Throws:

NoSuchAlgorithmException - if the algorithm does not exist in this JVM.

getFingerPrint

public static String getFingerPrint(String base64EncodedKey)

Returns the fingerprint of the given Base64 encoded key. The input string is not checked, so it might be any valid Base64 encoded content.

Parameters:

base64EncodedKey - a base64 encoded key.

Returns:

the fingerprint, e.g. "ab:ec:...."
