Package ecdsa implements the Elliptic Curve Digital Signature Algorithm, as defined in FIPS 186-3.
In the call graph viewer below, each node is a function belonging to this package and its children are the functions it calls—perhaps dynamically.
The root nodes are the entry points of the package: functions that may be called from outside the package. There may be non-exported or anonymous functions among them if they are called dynamically from another package.
Click a node to visit that function's source code.
From there you can visit its callers by
clicking its declaring
Functions may be omitted if they were determined to be unreachable in the particular programs or tests that were analyzed.
Sign signs an arbitrary length hash (which should be the result of hashing a larger message) using the private key, priv. It returns the signature as a pair of integers. The security of the private key depends on the entropy of rand.
Verify verifies the signature in r, s of hash using the public key, pub. Its return value records whether the signature is valid.
PrivateKey represents a ECDSA private key.
GenerateKey generates a public and private key pair.
PublicKey represents an ECDSA public key.
