New creates a Whisper client ready to communicate through the Ethereum P2P network.

NewEnvelope wraps a Whisper message with expiration and destination data included into an envelope for network forwarding.

NewFilterTopics creates a 2D topic array used by whisper.Filter from binary data elements.

NewFilterTopicsFlat creates a 2D topic array used by whisper.Filter from flat binary data elements.

NewFilterTopicsFromStrings creates a 2D topic array used by whisper.Filter from textual data elements.

NewFilterTopicsFromStringsFlat creates a 2D topic array used by whisper.Filter from flat binary data elements.

NewMessage creates and initializes a non-signed, non-encrypted Whisper message.

NewTopic creates a topic from the 4 byte prefix of the SHA3 hash of the data.

NewTopicFromString creates a topic using the binary data contents of the specified string.

NewTopics creates a list of topics from a list of binary data elements, by iteratively calling NewTopic on each of them.

NewTopicsFromStrings creates a list of topics from a list of textual data elements, by iteratively calling NewTopicFromString on each of them.

Envelope represents a clear-text data packet to transmit through the Whisper network.

Filter is used to subscribe to specific types of whisper messages.

Message represents an end-user data packet to transmit through the Whisper protocol.

Options specifies the exact way a message should be wrapped into an Envelope.

Whisper represents a dark communication interface through the Ethereum network, using its very own P2P communication layer.

Topic represents a cryptographically secure, probabilistic partial classifications of a message, determined as the first (left) 4 bytes of the SHA3 hash of some arbitrary data given by the original author of the message.
