Functions ¶

func BuildLogLeaf ¶

func BuildLogLeaf(logPrefix string,
	merkleLeaf ct.MerkleTreeLeaf, leafIndex int64,
	cert ct.ASN1Cert, chain []ct.ASN1Cert, isPrecert bool,
) (*trillian.LogLeaf, error)

BuildLogLeaf returns a Trillian LogLeaf structure for a (pre-)cert and the chain of certificates leading it up to a known root.

func BuildLogLeafWithChainHash ¶

func BuildLogLeafWithChainHash(logPrefix string, merkleLeaf ct.MerkleTreeLeaf, leafIndex int64, cert ct.ASN1Cert, chainHash []byte, isPrecert bool) (*trillian.LogLeaf, error)

BuildLogLeafWithChainHash returns a Trillian LogLeaf structure for a (pre-)cert and the chain of certificates leading it up to a known root.

func ExtraDataForChain ¶

func ExtraDataForChain(cert ct.ASN1Cert, chain []ct.ASN1Cert, isPrecert bool) ([]byte, error)

ExtraDataForChain creates the extra data associated with a log entry as described in RFC6962 section 4.6.

func ExtraDataForChainHash ¶

func ExtraDataForChainHash(cert ct.ASN1Cert, chainHash []byte, isPrecert bool) ([]byte, error)

ExtraDataForChainHash creates the extra data associated with a log entry as described in RFC6962 section 4.6 except the chain being replaced with its hash.

Types ¶

type FixedTimeSource ¶

type FixedTimeSource struct {
	// contains filtered or unexported fields
}

FixedTimeSource provides a fixed time for use in tests. It should not be used in production code.

func NewFixedTimeSource ¶

func NewFixedTimeSource(t time.Time) *FixedTimeSource

NewFixedTimeSource creates a FixedTimeSource instance

func (*FixedTimeSource) Now ¶

func (f *FixedTimeSource) Now() time.Time

Now returns the time value this instance contains

type SystemTimeSource ¶

type SystemTimeSource struct{}

SystemTimeSource provides the current system local time

func (SystemTimeSource) Now ¶

func (s SystemTimeSource) Now() time.Time

Now returns the true current local time.

type TimeSource ¶

type TimeSource interface {
	// Now returns the current time in real implementations or a suitable value in others
	Now() time.Time
}

TimeSource can provide the current time, or be replaced by a mock in tests to return specific values.
