public class LegacyBitsOfSecurityConstraint

extends ServicesConstraint

Legacy bits of security constraint. By default, legacy algorithms are all acceptable but can only be used for decryption and verification tasks. Algorithms with the required bits of security can be used for anything. If a minimum level of security is given for legacy algorithms, then anything below that will be treated as an error unless it appears in the exception list.

Constructor Summary

LegacyBitsOfSecurityConstraint(int requiredBitsOfSecurity)
Base constructor, legacy level is set to 0.

LegacyBitsOfSecurityConstraint(int requiredBitsOfSecurity, int legacyRequiredBitsOfSecurity)
Provide required bits of security and legacy requirements.

LegacyBitsOfSecurityConstraint(int requiredBitsOfSecurity, int legacyRequiredBitsOfSecurity, java.util.Set exceptions)
Provide required bits of security, legacy requirements, and a set of exceptions.

LegacyBitsOfSecurityConstraint(int requiredBitsOfSecurity, java.util.Set exceptions)
Provide required bits of security, and a set of exceptions.

Constructor Detail

LegacyBitsOfSecurityConstraint

public LegacyBitsOfSecurityConstraint(int requiredBitsOfSecurity)

Base constructor, legacy level is set to 0.

Parameters:

requiredBitsOfSecurity - required bits of security for encryption and signing operations.

LegacyBitsOfSecurityConstraint

public LegacyBitsOfSecurityConstraint(int requiredBitsOfSecurity,
                                      int legacyRequiredBitsOfSecurity)

Provide required bits of security and legacy requirements.

Parameters:

requiredBitsOfSecurity - required bits of security for encryption and signing operations.

legacyRequiredBitsOfSecurity - acceptable bits of security for decryption and verification operations.

LegacyBitsOfSecurityConstraint

public LegacyBitsOfSecurityConstraint(int requiredBitsOfSecurity,
                                      java.util.Set exceptions)
