Unable to use AEAD with shadowrocket iOS client

[alexyangjie]

What version of shadowsocks-libev are you using?

3.0.1

What operating system are you using?

CentOS 7

What did you do?

Use shadowrocket on iOS to connect to vps

What did you expect to see?

Connection successful

What did you see instead?

Unable to connect. Logs on server:
2017-02-10 09:29:40 ERROR: failed to handshake with [ip address removed]: authentication error

Nothing additional when running with -v.

ss-local on Windows (cygwin) works fine. The issue only occurred when using shadowrocket on iOS.

What is your config in detail (with all sensitive info masked)?

{
"server": ["[::0]", "0.0.0.0"],
"server_port": **,
"local_port": 8089,
"password": "****",
"timeout": 600,
"method": "aes-128-gcm"
}
/usr/local/bin/ss-server -a root -c /etc/shadowsocks-libev/config.json -u

To identify if it's a problem of shadowsocks-libev, you may try this port: https://github.com/shadowsocks/go-shadowsocks2

It is caused by iOS client

[maddie]

@debiansid If I understand SIP004 (shadowsocks/shadowsocks-org#30) correctly, aes-128-gcm is considered to be AEAD cipher thus will communicate in a different fashion under 3.0.1 server side.

Shadowrocket seems to be based on 2.x client, so it's not supported.

[debiansid]

@maddie agreed

[alexyangjie]

@madeye I've tested with go-shadowsocks2, and it still has issues. Looks like it is an issue with shadowrocket. I will close this issue now. Thanks for help.

AFAIK no client other than shadowsocks-libev and go-shadowsocks2 support AEAD ciphers (which is still in developing stage; see shadowsocks/shadowsocks-org#42)

Please wait for official announcement.

@riobard AES-*-GCM and ChaCha20-Poly1305 is implemented in Android-Client.
The go version is pretty interesting, though very hard to use.
I have to open the CMD every time I want to connect to server :D. Though works great ;).
It would be great, if there a wiki page, tracing SS clients, that which one has implement the AEAD ciphers.
