Class AEADBaseEngine.DataLimitCounter

java.lang.Object
  org.bouncycastle.crypto.engines.AEADBaseEngine.DataLimitCounter

Enclosing class:

org.bouncycastle.crypto.engines.AEADBaseEngine

protected static class AEADBaseEngine.DataLimitCounter

extends java.lang.Object

Enforces the AEAD confidentiality / data limit (q) of draft-irtf-cfrg-aead-limits sec. 5/6: it bounds the total bytes processed under one key (nonce + AAD + message), throwing once 2^n is exceeded. Reset only on key change. TODO: currently wired only by AsconAEAD128 (NIST SP 800-232); the other AEADBaseEngine subclasses do not bound per-key data volume.
