Francis Bacon created this method of hiding one message within another.It is not a true cipher, but just a way to conceal your secret text withinplain sight. The way it originally worked is that the writer would use twodifferent typefaces. One would be the 'A' typeface and the other would be'B'. Your message would be written with the two fonts intermingled, thushiding your message within a perfectly normal text.

• Ab Cipher Block

There are two versions. The first uses the same code for I and J, plusthe same code for U and V. The second uses distict codes for everyletter.

For example, let's take the message 'Test It' and encode it with thedistinct codes for each letter. You get a result like 'BAABBAABAABAABABAABBABAAABAABB'. Macbook pro software downloads. The original message is 6 characters long so the encodedversion is 6 * 5 = 30 characters. If I were to find a 30-character messageand put in 'B' letters as bold and italics, we will get 'Thisis a test message with bold for 'B'.'.

When decoding, it will use '0', 'A', and 'a' as an 'A'; '1', 'B', and 'b'are all equivalent as well. Other letters are ignored.

AB Cipher is based on a method used by Sir Francis Bacon to encipher messages. His method was published in 'De Augmentis Scientarium' in 1623 and described by Jason Fagone in his book about Elizebeth Friedman (and her husband, William) in 'The Woman Who Smashed Codes'.

Options

Ab Cipher Block

-A auth-username:password

Supply BASIC Authentication credentials to the server. The username and password are separated by a single : and sent on the wire base64 encoded. The string is sent regardless of whether the server needs it (i.e., has sent an 401 authentication needed).

-b windowsize

Size of TCP send/receive buffer, in bytes.

-B local-address

Address to bind to when making outgoing connections.

-c concurrency

Number of multiple requests to perform at a time. Default is one request at a time.

-C cookie-name=value

Add a Cookie: line to the request. The argument is typically in the form of a name=value pair. This field is repeatable.

-d

Do not display the 'percentage served within XX [ms] table'. (legacy support).

-e csv-file

Write a Comma separated value (CSV) file which contains for each percentage (from 1% to 100%) the time (in milliseconds) it took to serve that percentage of the requests. This is usually more useful than the 'gnuplot' file; as the results are already 'binned'.

-E client-certificate-file

When connecting to an SSL website, use the provided client certificate in PEM format to authenticate with the server. The file is expected to contain the client certificate, followed by intermediate certificates, followed by the private key. Available in 2.4.36 and later.

-f protocol

Specify SSL/TLS protocol (SSL2, SSL3, TLS1, TLS1.1, TLS1.2, or ALL). TLS1.1 and TLS1.2 support available in 2.4.4 and later.

-g gnuplot-file

Write all measured values out as a 'gnuplot' or TSV (Tab separate values) file. This file can easily be imported into packages like Gnuplot, IDL, Mathematica, Igor or even Excel. The labels are on the first line of the file.

-h

Display usage information.

-H custom-header

Append extra headers to the request. The argument is typically in the form of a valid header line, containing a colon-separated field-value pair (i.e., 'Accept-Encoding: zip/zop;8bit').

-i

Do HEAD requests instead of GET.

-k

Enable the HTTP KeepAlive feature, i.e., perform multiple requests within one HTTP session. Default is no KeepAlive.

-l

Do not report errors if the length of the responses is not constant. This can be useful for dynamic pages. Available in 2.4.7 and later.

-m HTTP-method

Custom HTTP method for the requests. Available in 2.4.10 and later.

-n requests

Number of requests to perform for the benchmarking session. The default is to just perform a single request which usually leads to non-representative benchmarking results.

-p POST-file

File containing data to POST. Remember to also set -T.

-P proxy-auth-username:password

Supply BASIC Authentication credentials to a proxy en-route. The username and password are separated by a single : and sent on the wire base64 encoded. The string is sent regardless of whether the proxy needs it (i.e., has sent an 407 proxy authentication needed).

-q

When processing more than 150 requests, ab outputs a progress count on stderr every 10% or 100 requests or so. The -q flag will suppress these messages.

-r

Don't exit on socket receive errors.

-s timeout

Maximum number of seconds to wait before the socket times out. Default is 30 seconds. Available in 2.4.4 and later.

-S

Do not display the median and standard deviation values, nor display the warning/error messages when the average and median are more than one or two times the standard deviation apart. And default to the min/avg/max values. (legacy support).

-t timelimit

Maximum number of seconds to spend for benchmarking. This implies a -n 50000 internally. Use this to benchmark the server within a fixed total amount of time. Per default there is no timelimit.

-T content-type

Content-type header to use for POST/PUT data, eg. application/x-www-form-urlencoded. Default is text/plain.

-u PUT-file

File containing data to PUT. Remember to also set -T.

-v verbosity

Set verbosity level - 4 and above prints information on headers, 3 and above prints response codes (404, 200, etc.), 2 and above prints warnings and info.

-V

Display version number and exit.

-w

Print out results in HTML tables. Default table is two columns wide, with a white background.

-x <table>-attributes

String to use as attributes for <table>. Attributes are inserted <table here >.

-X proxy[:port]

Use a proxy server for the requests.

-y <tr>-attributes

String to use as attributes for <tr>.

-z <td>-attributes

String to use as attributes for <td>.

-Z ciphersuite

Specify SSL/TLS cipher suite (See openssl ciphers)
