Method Detail

hashString

public static java.lang.String hashString(@NotNull
                                          java.lang.String content)

Hashes the string

Parameters:

content - A string to hash, not null

Returns:

A string representing the hash

hashAsString

public static java.lang.String hashAsString(@NotNull
                                            byte[] inputBytes)

Returns a hashed string of the input bytes

Parameters:

inputBytes - The input bytes to hash

Returns:

The hashed value as a string

hashAsString

public static java.lang.String hashAsString(@NotNull
                                            byte[] inputBytes,
                                            java.lang.String hashAlgorithm)
                                     throws java.security.NoSuchAlgorithmException

Returns a hashed string of the input bytes using a specified hash algorithm. This is useful if you need a long-term solution. The library might change the default hash between versions

Parameters:

inputBytes - The input bytes to hash

hashAlgorithm - The algorithm to use for hashing

Returns:

The hashed value as a string

Throws:

java.security.NoSuchAlgorithmException - If the algorithm specified doesn't exist

hash

public static java.math.BigInteger hash(@NotNull
                                        byte[] inputBytes,
                                        java.lang.String hashAlgorithm)
                                 throws java.security.NoSuchAlgorithmException

Returns a hashed number for the input bytes, using a specified hash algorithm. This is useful if you need a long-term solution. The library might change the default hash between versions

Parameters:

inputBytes - The input bytes to hash

hashAlgorithm - The algorithm to use for hashing

Returns:

The hashed value, as a BigInteger

Throws:

java.security.NoSuchAlgorithmException - If the algorithm specified doesn't exist
