The procedure to read the binary text is straightforward. The binary text must be segregated into 8-bit chunks that become individual symbols or alphabets. The corresponding symbol for each 8-bit chunk in theASCII tableis noted and the sentences are formed, much like a puzzle. An ASCII table...
Hexadecimal to decimal conversionis done by keeping the base numbers of both number systems in mind. While converting hexadecimal to decimal, the base number 16 is used. The hexadecimal number system uses 16 digits/alphabets: The digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and the character...
Strings in Python are immutable means they cannot be changed once defined.Special characters are characters other than alphabets. The set contains "[@_!#$%^&*()<>?/\|}{~:] ".Checking if a string contains any special characterTo check for the presence of any special character in a ...
necessarily miscounted; any character that is not a letter from a certain set of alphabets is counted as both upper and lower case by this code. To remedy this, we could add a line at the beginning of the repeat loop to pass over characters that do not have distinct upper and lowercase...
In the late 1500s, Blaise de Vigenère proposed a polyalphabetic system that is particularly difficult to decipher. His method used a combination of the Trimethius tableau and akey. The key determined which of the alphabets in the table the decipherer should use, but wasn't necessarily pa...

We know that the alphabets are a total of {eq}26 {/eq}. In this case, first, we form four-letter strings that begin with {eq}t {/eq}. So, the... Learn more about this topic: Permutation | Definition & Examples from Chapter 22/ Lesson 6 ...
Convert a Character to Uppercase/Lowercase Using Binary Operations and Hexadecimal As every character has an ASCII value and a binary representation, we can perform binary operations. We use the hexadecimal0x5fwhose binary representation is 1011111 and0x20representing 0100000 in binary. ...

We can use therand()function to generate a random password in PHP. Therand()function returns a random integer from the range of the parameters provided. The function takes two integer values as the parameters. We can define a string of the alphabets and numbers from where we can combine th...
