Constructor Detail

DigestAlgorithmBuilder

protected DigestAlgorithmBuilder()

Method Detail

getAlgorithm

protected abstract String getAlgorithm()

Gets a name of algorithm supported by digest.

Returns:

algorithm name

bytesRepresentation

public DigestAlgorithmBuilder bytesRepresentation(BytesRepresentation bytesRepresentation)

Sets how byte arrays will be represented in strings. By default HexRepresentation is used.

Parameters:

bytesRepresentation - byte array representation strategy

Returns:

this instance

encoding

public DigestAlgorithmBuilder encoding(String encoding)

Sets encoding for strings in input and output.

Parameters:

encoding - encoding to be set

Returns:

this instance

salted

public SaltingAdapterBuilder salted()

Builds a hashing algorithm and wraps it by salting adapter builder. Salting adapter automatically gets the same encoding as hashing algorithm.

Returns:

salting adapter builder

salted

public SaltingAdapterBuilder salted(CombineAlgorithm combineAlgorithm)

Builds a hashing algorithm and wraps it by salting adapter builder with custom combine algorithm. Salting adapter automatically gets the same encoding as hashing algorithm.

Parameters:

combineAlgorithm - combine algorithm for input text and salt

Returns:

salting adapter builder

repeated

public RepeatingDecoratorBuilder repeated(int repeats)

Builds a hashing algorithm and wraps it into repeating decorator builder.

Parameters:

repeats - count of repeats

Returns:

repeating decorator builder

build

public HashingAlgorithm build()
                       throws EncryptionException

Description copied from interface: HashingAlgorithmBuilder

Builds a new instance of hashing algorithm.

Specified by:

build in interface HashingAlgorithmBuilder

Returns:

algorithm instance

Throws:

EncryptionException
