KeyGenAlgorithm

protected KeyGenAlgorithm(int oidTag,
                          java.lang.String name,
                          KeyGenAlgorithm.KeyStrengthValidator keyStrengthValidator,

Method Detail

fromOID

public static KeyGenAlgorithm fromOID(OBJECT_IDENTIFIER oid)
                               throws java.security.NoSuchAlgorithmException

Throws:

java.security.NoSuchAlgorithmException

isValidStrength

public boolean isValidStrength(int strength)

Parameters:

strength - Key strength.

Returns:

true if the given strength is valid for this key generation algorithm. Note that PBE algorithms require PBEParameterSpecs rather than strengths. It is the responsibility of the caller to verify this.
