+ <b>--decrypt=(true|nostash|auto|false)</b>
+ If <b>true</b>, when encountering an encrypted message, try to decrypt
+ it while indexing, and stash any discovered session keys. If
+ <b>auto</b>, try to use any session key already known to belong to this
+ message, but do not attempt to use the user's secret keys. If
+ decryption is successful, index the cleartext of the message.
+
+ Be aware that the index is likely sufficient (and the session
+ key is certainly sufficient) to reconstruct the cleartext of the
+ message itself, so please ensure that the notmuch message index
+ is adequately protected. DO NOT USE <b>--decrypt=true</b> or
+ <b>--decrypt=nostash</b> without considering the security of your
+ index.
