Class Argon2HashProvider.Parameters

java.lang.Object

org.apache.shiro.crypto.support.hashes.argon2.Argon2HashProvider.Parameters

Enclosing class:

Argon2HashProvider

public static final class Argon2HashProvider.Parameters
extends Object

Parameters for the Argon2Hash class.

This class contains public constants only. The constants starting with PARAMETER_ are the parameter names recognized by the HashSpi.HashFactory.generate(HashRequest) method.

The constants starting with DEFAULT_ are their respective default values.

• Constant Field Values

DEFAULT_ALGORITHM_VERSION

public static final int DEFAULT_ALGORITHM_VERSION

Default algorithm version.

See Also:

• Constant Field Values

DEFAULT_ITERATIONS

public static final int DEFAULT_ITERATIONS

Default iterations.

See Also:

• Constant Field Values

DEFAULT_MEMORY_KIB

public static final int DEFAULT_MEMORY_KIB

Default memory kib.

See Also:

• Constant Field Values

DEFAULT_PARALLELISM

public static final int DEFAULT_PARALLELISM

Default parallelism number.

• Constant Field Values

PARAMETER_ALGORITHM_NAME

public static final String PARAMETER_ALGORITHM_NAME

Parameter for modifying the internal algorithm used by Argon2.

Valid values are argon2i (optimized to resist side-channel attacks), argon2d (maximizes resistance to GPU cracking attacks) and argon2id (a hybrid version).

The default value is "argon2id" when this parameter is not specified.

See Also:

• Constant Field Values

PARAMETER_ALGORITHM_VERSION

public static final String PARAMETER_ALGORITHM_VERSION

Argon2 algorithm version.

See Also:

• Constant Field Values

PARAMETER_SALT

public static final String PARAMETER_SALT

The salt to use.

The value for this parameter accepts a Base64-encoded 16byte (128bit) salt.

As for any KDF, do not use a static salt value for multiple passwords.

The default value is a new random 128bit-salt, if this parameter is not specified.

See Also:

• Constant Field Values

PARAMETER_ITERATIONS

public static final String PARAMETER_ITERATIONS

Argon2 parameter iterations.

See Also:

• Constant Field Values

PARAMETER_MEMORY_KIB

public static final String PARAMETER_MEMORY_KIB

Argon2 parameter memory kib.

See Also:

• Constant Field Values

PARAMETER_PARALLELISM

public static final String PARAMETER_PARALLELISM

Argon2 parameter parallelism.

See Also:

• Constant Field Values

PARAMETER_OUTPUT_LENGTH_BITS

public static final String PARAMETER_OUTPUT_LENGTH_BITS

The output length (in bits) of the resulting data section.

Argon2 allows to modify the length of the generated output.

The default value is 256 when this parameter is not specified.
