It + | watches TCP connections and displays the data going by. If a connection is + | SSL, the data display includes interpreted SSL records and handshaking + + Options + + -v + + Print a version string for the tool. + + -h + + | Turn on hex/ASCII printing. Instead of outputting raw data, the + | command interprets each record as a numbered line of hex values, + | followed by the same data as ASCII characters. The two parts are + | separated by a vertical bar. Nonprinting characters are replaced + | by dots. + + -f + + | Turn on fancy printing. Output is printed in colored HTML. Data + | sent from the client to the server is in blue; the server's reply + | is in red. When used with looping mode, the different connections + | are separated with horizontal lines. You can use this option to + | upload the output into a browser. + + -s + + | Turn on SSL parsing and decoding. The tool does not automatically + | detect SSL sessions. If you are intercepting an SSL connection, + | use this option so that the tool can detect and decode SSL + | structures. + + | If the tool detects a certificate chain, it saves the DER-encoded + | certificates into files in the current directory. The files are + | named cert.0x, where x is the sequence number of the certificate. + + | If the -s option is used with -h, two separate parts are printed + | for each record: the plain hex/ASCII output, and the parsed SSL + | output. + + -x + + | Turn on hex/ASCII printing of undecoded data inside parsed SSL + | records. Used only with the -s option. This option uses the same + | output format as the -h option. + + -l prefix + + | Turn on looping; that is, continue to accept connections rather + | than stopping after the first connection is complete. + + -p port + + Change the default rendezvous port (1924) to another port. + + The following are well-known port numbers: + + \* HTTP 80 + + \* HTTPS 443 + + \* SMTP 25 + + \* FTP 21 + + \* IMAP 143 + + \* IMAPS 993 (IMAP over SSL) + + \* NNTP 119 + + \* NNTPS 563 (NNTP over SSL) + + Usage and Examples + + | You can use the SSL Debugging Tool to intercept any connection + | information. Although you can run the tool at its most basic by issuing + | the ssltap command with no options other than hostname:port, the + | information you get in this way is not very useful. For example, assume + | your development machine is called intercept. The simplest way to use the + | debugging tool is to execute the following command from a command shell: + + $ ssltap www.netscape.com + + | The program waits for an incoming connection on the default port 1924. In + | your browser window, enter the URL http://intercept:1924. The browser + | retrieves the requested page from the server at www.netscape.com, but the + | page is intercepted and passed on to the browser by the debugging tool on + | intercept. On its way to the browser, the data is printed to the command + | shell from which you issued the command. Data sent from the client to the + | server is surrounded by the following symbols: --> [ data ] Data sent from + | the server to the client is surrounded by the following symbols: "left + | arrow"-- [ data ] The raw data stream is sent to standard output and is + | not interpreted in any way. This can result in peculiar effects, such as + | sounds, flashes, and even crashes of the command shell window. To output a + | basic, printable interpretation of the data, use the -h option, or, if you + | are looking at an SSL connection, the -s option. You will notice that the + | page you retrieved looks incomplete in the browser. This is because, by + | default, the tool closes down after the first connection is complete, so + | the browser is not able to load images. To make the tool continue to + | accept connections, switch on looping mode with the -l option. The + | following examples show the output from commonly used combinations of + | options. + + Example 1 + + $ ssltap.exe -sx -p 444 interzone.mcom.com:443 > sx.txt + + Output + + | Connected to interzone.mcom.com:443 + | -->; [ + | alloclen = 66 bytes + | [ssl2] ClientHelloV2 { + | version = {0x03, 0x00} + | cipher-specs-length = 39 (0x27) + | sid-length = 0 (0x00) + | challenge-length = 16 (0x10) + | cipher-suites = { + + | (0x010080) SSL2/RSA/RC4-128/MD5 + | (0x020080) SSL2/RSA/RC4-40/MD5 + | (0x030080) SSL2/RSA/RC2CBC128/MD5 + | (0x040080) SSL2/RSA/RC2CBC40/MD5 + | (0x060040) SSL2/RSA/DES64CBC/MD5 + | (0x0700c0) SSL2/RSA/3DES192EDE-CBC/MD5 + | (0x000004) SSL3/RSA/RC4-128/MD5 + | (0x00ffe0) SSL3/RSA-FIPS/3DES192EDE-CBC/SHA + | (0x00000a) SSL3/RSA/3DES192EDE-CBC/SHA + | (0x00ffe1) SSL3/RSA-FIPS/DES64CBC/SHA + | (0x000009) SSL3/RSA/DES64CBC/SHA + | (0x000003) SSL3/RSA/RC4-40/MD5 + | (0x000006) SSL3/RSA/RC2CBC40/MD5 + | } + | session-id = { } + | challenge = { 0xec5d 0x8edb 0x37c9 0xb5c9 0x7b70 0x8fe9 0xd1d3 + + | 0x2592 } + | } + | ] + | <-- [ + | SSLRecord { + | 0: 16 03 00 03 e5 \|..... + | type = 22 (handshake) + | version = { 3,0 } + | length = 997 (0x3e5) + | handshake { + | 0: 02 00 00 46 \|...F + | type = 2 (server_hello) + | length = 70 (0x000046) + | ServerHello { + | server_version = {3, 0} + | random = {...} + | 0: 77 8c 6e 26 6c 0c ec c0 d9 58 4f 47 d3 2d 01 45 \| + | wn&l.ì..XOG.-.E + | 10: 5c 17 75 43 a7 4c 88 c7 88 64 3c 50 41 48 4f 7f \| + + | \\.uC§L.Ç.d<PAHO. + | session ID = { + | length = 32 + + | contents = {..} + | 0: 14 11 07 a8 2a 31 91 29 11 94 40 37 57 10 a7 32 \| ...¨*1.)..@7W.§2 + | 10: 56 6f 52 62 fe 3d b3 65 b1 e4 13 0f 52 a3 c8 f6 \| VoRbþ=³e±...R£È. + | } + | cipher_suite = (0x0003) SSL3/RSA/RC4-40/MD5 + | } + | 0: 0b 00 02 c5 \|...Å + | type = 11 (certificate) + | length = 709 (0x0002c5) + | CertificateChain { + | chainlength = 706 (0x02c2) + | Certificate { + | size = 703 (0x02bf) + | data = { saved in file 'cert.001' } + | } + | } + | 0: 0c 00 00 ca \|.... + | type = 12 (server_key_exchange) + | length = 202 (0x0000ca) + | 0: 0e 00 00 00 \|.... + | type = 14 (server_hello_done) + | length = 0 (0x000000) + | } + | } + | ] + | --> [ + | SSLRecord { + | 0: 16 03 00 00 44 \|....D + | type = 22 (handshake) + | version = { 3,0 } + | length = 68 (0x44) + | handshake { + | 0: 10 00 00 40 \|...@ + | type = 16 (client_key_exchange) + | length = 64 (0x000040) + | ClientKeyExchange { + | message = {...} + | } + | } + | } + | ] + | --> [ + | SSLRecord { + | 0: 14 03 00 00 01 \|..... + | type = 20 (change_cipher_spec) + | version = { 3,0 } + | length = 1 (0x1) + | 0: 01 \|. + | } + | SSLRecord { + | 0: 16 03 00 00 38 \|....8 + | type = 22 (handshake) + | version = { 3,0 } + | length = 56 (0x38) + | < encrypted > + + | } + | ] + | <-- [ + | SSLRecord { + | 0: 14 03 00 00 01 \|..... + | type = 20 (change_cipher_spec) + | version = { 3,0 } + | length = 1 (0x1) + | 0: 01 \|. + | } + | ] + | <-- [ + | SSLRecord { + | 0: 16 03 00 00 38 \|....8 + | type = 22 (handshake) + | version = { 3,0 } + | length = 56 (0x38) + | < encrypted > + + | } + | ] + | --> [ + | SSLRecord { + | 0: 17 03 00 01 1f \|..... + | type = 23 (application_data) + | version = { 3,0 } + | length = 287 (0x11f) + | < encrypted > + | } + | ] + | <-- [ + | SSLRecord { + | 0: 17 03 00 00 a0 \|.... + | type = 23 (application_data) + | version = { 3,0 } + | length = 160 (0xa0) + | < encrypted > + + | } + | ] + | <-- [ + | SSLRecord { + | 0: 17 03 00 00 df \|....ß + | type = 23 (application_data) + | version = { 3,0 } + | length = 223 (0xdf) + | < encrypted > + + | } + | SSLRecord { + | 0: 15 03 00 00 12 \|..... + | type = 21 (alert) + | version = { 3,0 } + | length = 18 (0x12) + | < encrypted > + | } + | ] + | Server socket closed. + + Example 2 + + | The -s option turns on SSL parsing.
