Method Detail

equals

public boolean equals(java.lang.Object obj)

The typecode identifies the parameter set: the rest of the values are derived from it.

The instances are interned - every lookup hands back one of the static fields - so this agrees with the reference equality it replaces. It states the intent instead of leaving callers to rely on the interning.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

getType

public int getType()

getH

public int getH()

getSecurityCategory

public int getSecurityCategory()

Return the NIST security category of this parameter set: 3 for the SHA-256/192 and SHAKE256/192 sets (m = 24) and 5 for the SHA-256 and SHAKE256/256 sets (m = 32) (NIST IR 8547, Table 3).

Specified by:

getSecurityCategory in interface PQCParameters

Returns:

the security category, as given in NIST IR 8547 Tables 3 and 5.

getClassicalSecurityStrength

public int getClassicalSecurityStrength()

Return the classical security strength of this parameter set: 8 times the hash output length m, so 192 or 256 bits (NIST IR 8547, Table 3).

Specified by:

getClassicalSecurityStrength in interface PQCParameters

Returns:

the classical security strength in bits.

getM

public int getM()

getDigestOID

public ASN1ObjectIdentifier getDigestOID()

getParametersForType

public static LMSigParameters getParametersForType(int type)
