sslsniff-bpfcc(8)


NAME

   sslsniff - Print data passed to OpenSSL. Uses Linux eBPF/bcc.

SYNOPSIS

   sslsniff

DESCRIPTION

   sslsniff  prints data sent to SSL_write and SSL_read OpenSSL functions,
   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 and SSL_read system-wide:
          # sslsniff

FIELDS

   FUNC   Which function is being called (SSL_write or SSL_read)

   TIME   Time of the command, in seconds.

   COMM   Entered command.

   PID    Process ID calling OpenSSL.

   LEN    Bytes written or read by OpenSSL functions.

SOURCE

   This is from bcc.

          https://github.com/iovisor/bcc

   Also  look  in  the bcc distribution for a companion _examples.txt file
   containing example usage, output, and commentary for this tool.

OS

   Linux

STABILITY

   Unstable - in development.
