Class HashManager

  • public final class HashManager
extends Manager
    Manager that can be used to determine support for hash functions. By default the Manager announces support for XEP-0300, as well as for the recommended set of hash algorithms. Those contain SHA256, SHA384, SHA512, SHA3-256, SHA3-384, SHA3-512, BLAKE2B256, BLAKE2B384 and BLAKE2B512. Those algorithms got recommended here: https://xmpp.org/extensions/xep-0300.html#recommendations.
