---|---|
static void |
clearCache() |
static SigningPublicKey |
create(byte[] data,
int off)
Pull from cache or return new.
|
static SigningPublicKey |
create(InputStream in)
Pull from cache or return new
|
boolean |
equals(Object obj)
Warning - this returns true for two different classes with the same size
and same data, e.g.
|
byte[] |
getPadding(KeyCertificate kcert)
Get the portion of this (type 0) SPK that is really padding based on the Key Cert type given,
if any
|
SigType |
getType() |
int |
hashCode()
We assume the data has enough randomness in it, so use the first 4 bytes for speed.
|
int |
length()
The legal length of the byte array in this data structure
|
String |
toString() |
SigningPublicKey |
toTypedKey(KeyCertificate kcert)
Up-convert this from an untyped (type 0) SPK to a typed SPK based on the Key Cert given.
|
void |
writeTruncatedBytes(OutputStream out)
Write the data up to a max of 128 bytes.
