Functions for performing the core cryptographic operations for AKD

Functions

compute_fresh_azks_value
Used by the server to produce a commitment for an AkdLabel, version, and AkdValue
compute_parent_hash_from_children
Computes the parent hash from the children hashes and labels
compute_root_hash_from_val
Given the top-level hash, compute the “actual” root hash that is published by the directory maintainer
empty_node_hash
AZKS value corresponding to an empty node
empty_root_value
The value stored in the root node upon initialization, with no children
get_commitment_nonce
Used by the server to produce a commitment nonce for an AkdLabel, version, and AkdValue. Computes nonce = H(commitment key || label)
hash_leaf_with_commitment
Hash a commit and epoch together to get the leaf’s hash value
stale_azks_value
Similar to commit_fresh_value, but used for stale values.
