方法详细资料
- isCanonical
  
  public boolean isCanonical()
  
  返回:
  
  true if the S component is "low", that means it is below
- toCanonicalised
  
  public ECDSASignature toCanonicalised()
  
  Will automatically adjust the S component to be less than or equal to half the curve order, if necessary. This is required because for every signature (r,s) the signature (r, -s (mod N)) is a valid signature of the same message. However, we dislike the ability to modify the bits of a Bitcoin transaction after it's been signed, as that violates various assumed invariants. Thus in future only one of those forms will be considered legal and the other will be banned.
  
  返回:
  
  the signature in a canonicalised form.
