Method Detail

getHkdf

public at.favre.lib.crypto.HKDF getHkdf()

Description copied from interface: Version

What HKDF version to use (ie. which mac implementation is used)

Specified by:

getHkdf in interface Version

Returns:

HKDF instance

getHashByteLength

public int getHashByteLength()

Description copied from interface: Version

Gets the used bcrypt hash byte length. This is usually 23 or 24 bytes. Choose if you want to use a more compatible approach (using only 23 byte output from bcrypt) or a more correct approach (using the full 24 byte blowfish provides) of using the underlying bcrypt hash.

Specified by:

getHashByteLength in interface Version

Returns:

length of the used bcrypt hash (23 or 24 byte)

getVersionCode

public byte getVersionCode()

Description copied from interface: Version

The version code used to identify the configuration

Specified by:

getVersionCode in interface Version

Returns:

as byte

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
