      org.bouncycastle.asn1.x509.MTCCertificationAuthority

All Implemented Interfaces:

ASN1Encodable, Encodable

public class MTCCertificationAuthority

extends ASN1Object

ASN.1 structure for the extension defined in Section 5.5 of draft-ietf-plants-merkle-tree-certs: MTCCertificationAuthority ::= SEQUENCE { logHash AlgorithmIdentifier{DIGEST-ALGORITHM, {[]}}, sigAlg AlgorithmIdentifier{SIGNATURE-ALGORITHM, {[]}}, minSerial INTEGER (0..mtcMaxSerial), maxSerial INTEGER (0..mtcMaxSerial) }

is the hash algorithm used by all issuance logs operated by this CA. is the CA cosigner's signature algorithm. and are the inclusive bounds of the cert serial range this CA is authorized for; per Section 6.1 of the draft a serial encodes the log number in its upper 16 bits and the entry index in the lower 48 bits (a 64-bit value), so the range can constrain either.

Field Summary

static java.math.BigInteger

MAX_SERIAL - the largest legal serial, 2^64 - 1 (a serial is the 64-bit composition of a 16-bit log number and a 48-bit entry index).
