# Check TLS Suites

Provides list of TLS suite names and recommendation status per IANA given either:

- A hex stream of cipher suites like one might extract in Wireshark from a TLS Client Hello, or
- A comma-separated list of integers representing cipher suites as one might extract with `tshark -r some-special.pcap -Y 'tls.handshake.ciphersuites' -T fields -e 'tls.handshake.ciphersuite'`

## Options
```
check-tls-suites -h
Check TLS Suites 0.1.8
Anthony J. Martinez <anthony@ajmartinez.com>
Displays TLS cipher suite names and recommendation status from IANA for a set of given ciphers

USAGE:
    check-tls-suites [FLAGS] -f <from_file> -w --hex-stream <hex_stream> --int-list <int_list>

FLAGS:
    -w               Download the IANA TLS parameters CSV from https://www.iana.org/assignments/tls-parameters/tls-parameters-4.csv
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -f <from_file>                   Path to the IANA TLS parameters CSV
        --hex-stream <hex_stream>    Provide the hex stream of cipher specs (from Wireshark for example)
        --int-list <int_list>        Provide a comma-separated list of cipher spec integer representations (from tshark
                                     for example
```
