sslsniff(8)

NAME
sslsniff - Print data passed to OpenSSL, GnuTLS or NSS. Uses Linux eBPF/bcc.

SYNOPSIS
sslsniff [-h] [-p PID] [-c COMM] [-o] [-g] [-n] [-d]

DESCRIPTION
sslsniff prints data sent to write/send and read/recv functions of OpenSSL, GnuTLS and NSS, allowing us to read plain text content before encryption (when writing) and after decryption (when reading). This works reading the second parameter of both functions (*buf). Since this uses BPF, only the root user can use this tool.

REQUIREMENTS
CONFIG_BPF and bcc.

EXAMPLES

Print all calls to SSL write/send and read/recv system-wide:
    # sslsniff
