Module akd_client::crypto

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.
