Chore(deps): Bump github.com/refraction-networking/utls from 1.3.1 to 1.3.2

[dependabot]

Bumps github.com/refraction-networking/utls from 1.3.1 to 1.3.2.

Release notes

Sourced from github.com/refraction-networking/utls's releases.

v1.3.2 bug fixes, robustness, and new (beta) ClientHelloSpecs

What's Changed

• fixes #127 by @​fqrious in refraction-networking/utls#175
• Implement ClientHelloSpec JSON Unmarshaler by @​gaukas in refraction-networking/utls#176
• fix: PSK extension w/o session cache crashing by @​gaukas in refraction-networking/utls#177
• fix: connection state locked never called by @​blakebyrnes in refraction-networking/utls#178
• fix: don't shuf psk by @​gaukas in refraction-networking/utls#180

Note

Added HelloChrome_100_PSK and HelloChrome_112_PSK_Shuf, which includes PreSharedKey automatically instead of Padding as the last TLS extensions.

To use them correctly, you are required to use (*UConn).ApplyPreset():

conn := utls.UClient(plainConn, utlsConfig, utls.HelloCustom)
preset, err := utls.UTLSIdToSpec(utls.HelloChrome_112_PSK_Shuf) // correct
if err != nil {
	return nil, err
}
if pskExt, ok := preset.Extensions[len(preset.Extensions)-1].(*utls.FakePreSharedKeyExtension); ok {
	pskExt.PskIdentities = []utls.PskIdentity{ // must set identity
		{
			Label:               []byte("blahblahblah"), // change this
			ObfuscatedTicketAge: 0, // change this
		},
	}
	// each fake binder is 32 bytes of zeros
	pskExt.PskBinders = [][]byte{ // must set psk binders
		{
			0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,  // change this
		},
	} // byte slices
}
conn.ApplyPreset(&preset) // make sure to apply preset to the connection

Instead of

conn := utls.UClient(plainConn, utlsConfig, utls.HelloChrome_112_PSK_Shuf) // incorrect! PSK extension will use empty payload!
