build(deps): bump github.com/libp2p/go-libp2p-core from 0.3.0 to 0.5.0

[dependabot-preview]

Bumps github.com/libp2p/go-libp2p-core from 0.3.0 to 0.5.0.

Release notes

Sourced from github.com/libp2p/go-libp2p-core's releases.

v0.5.0

Hot on the heals on 0.4.0, we're releasing 0.5.0 with another breaking change. To better support per-transport "protector" protocols, we've removed the Protector interface in favor of just passing around a pre-shared key. That way, transports can choose how they wish to use the pre-shared key.

Note: Transports should avoid using the pre-shared key directly. They should treat it as a source of randomness and derive a new key using some transport-specific constant/nonce and a cryptographic hash function.

v0.4.0

Major features

Signed envelopes and peer records

The record package now includes the Record and Envelope data types, and related functions. An Envelope that allows libp2p peers to certify data such as addresses, capabilities, protocol support, etc. Such payloads are called Records.

The peer package now offers the PeerRecord record type. It implements the record.Record interface, and enables nodes to certify their own addresses to peers in a sequentially versioned manner.

Peerstore support for certified peer records

The peerstore package now offers the CertifiedAddrBook interface, which peerstores supporting certified peer records can implement to enable users to consume and query certified peer records from the network.

Use the peerstore.GetCertifiedAddrBook() function to attempt to downcast an ordinary peerstore.AddrBook implementation to its certified counterpart.

Other changes

• New crypto.PubKeyToStdKey and crypto.PrivKeyToStdKey functions to convert from libp2p keys to their stdlib counterparts.
• Minor eventbus events refactoring.
• Dependency upgrades.

v0.3.1

• Update dependencies
• In the insecure testing transport, use the reported remote ID instead of computing it.
• Cache serialized public keys to reduce CPU usage when establishing connections.
• Add additional events:
  • Identify
  • NAT status changes
