Constructor Detail

KeyUsage

public KeyUsage(byte[] bitString)

Creates a new instance with the given bit string, where each bit is one of the constants defined in the KeyUsageBits enumeration.

Parameters:

bitString - Octets making up key usage bit string.

KeyUsage

public KeyUsage(int flags)

Creates a new instance from OR-ing KeyUsageBits bitmask values.

Parameters:

flags - Bit mask created by OR-ing the bitmask of KeyUsageBits enum values together, e.g. KeyUsageBits.DigitalSignature.getMask()|KeyUsageBits.KeyCertSign.getMask()

KeyUsage

public KeyUsage(KeyUsageBits[] bits)

Creates a new instance that has all the given KeyUsageBits set.

Parameters:

bits - Array of KeyUsageBits describing all key usage bits to be set.

Method Detail

getUses

public Collection<KeyUsageBits> getUses()

Gets a collection of the bits set for this instance.

Returns:

Collection of KeyUsageBits items representing the bits that are set for this instance.

toString

public String toString()

Overrides:

toString in class Object

Returns:

List of all key usage bits set in this object, e.g. [DigitalSignature, KeyCertSign].
