    # File lib/net/ssh/userauth/methods/publickey.rb, line 37
37:           def initialize( buffers )
38:             @buffers = buffers
39:           end
Public Instance methods
authenticate( next_service, username, data={} )

Attempts to perform public-key authentication for the given username, trying each identity known to the key manager. If any of them succeed, returns true, otherwise returns false. The data hash must contain a UserKeyManager instance under the :key_manager key.

    # File lib/net/ssh/userauth/methods/publickey.rb, line 46
46:           def authenticate( next_service, username, data={} )
47:             key_manager = data[:key_manager]
48:             return false unless key_manager
49: 
50:             key_manager.identities.each do |identity|
51:               return true if authenticate_with( identity, next_service,
52:                 username, key_manager )
53:             end
54: 
55:             return false
56: 
57:           ensure
58:             key_manager.finish if key_manager
59:           end
