Internal call graph ▾
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.
const ( // KeySize is the size of the key used by this AEAD, in bytes. KeySize = 32 // NonceSize is the size of the nonce used with this AEAD, in bytes. NonceSize = 12 )
func New(key byte) (cipher.AEAD, error)
New returns a ChaCha20-Poly1305 AEAD that uses the given, 256-bit key.
