Demonstrations of sslsniff.py
This tool traces the write/send and read/recv functions of OpenSSL,
GnuTLS and NSS. Data passed to this functions is printed as plain
text. Useful, for example, to sniff HTTP before encrypted with SSL.
Output of tool executing in other shell "curl https://example.com"

USAGE message:
usage: sslsniff.py [-h] [-p PID] [-c COMM] [-o] [-g] [-n] [-d]
Sniff SSL data
optional arguments:
-h, --help show this help message and exit
-p PID, --pid PID sniff this PID only.
-c COMM, --comm COMM sniff only commands matching string.
-o, --no-openssl do not show OpenSSL calls.
-g, --no-gnutls do not show GnuTLS calls.
-n, --no-nss do not show NSS calls.
-d, --debug debug mode.
examples:
./sslsniff # sniff OpenSSL and GnuTLS functions
./sslsniff -p 181 # sniff PID 181 only
./sslsniff -c curl # sniff curl command only
./sslsniff --no-openssl # don't show OpenSSL calls
./sslsniff --no-gnutls # don't show GnuTLS calls
./sslsniff --no-nss # don't show NSS calls
