Numbers Converter & Encoder
- To use this tool, just input a value in any field and press the
- Your input should only include numbers and/or letters. Everything else will be removed.
- Conversions involving letters are case sensitive.
- There are many base62 alphabet implementations out there, typically
- Of these, the first two are widely used due to working compatibilities with other base encoding systems.
- Our tool supports all of them, with [0-9a-zA-Z] being the default one. We recommend the first two when working with lower bases.
- Regardless of which base62 alphabet is used, to convert to lower bases, we define the base2 to base61 alphabets as subsets of the base62 alphabet utilized.
- Upon a submission, the tool searches for the input characters in the corresponding alphabet or subalphabet. If they all are found, the one-to-many conversions take place; otherwise the tool returns all mismatched characters and advices users on how to proceed.
- Researchers, teachers, students, or anyone working with data conversions.
- Generate one-to-many maps for the strings trump, republicans, satan, 666, etc
- Repeat previous exercise, but this time for google, microsoft, yahoo...
- Consider a base26 number system wherein the upper case letters of the alphabets are the digits; i.e. A=0, B=1, C=2, ... Z=25. Convert the number hapg from base26 to base10 with this number system and with our tool. Explain any difference between the results.
- Password Constructions. Using our tool, the name johndoe in base25 is 6komo0e in base30. In addition, 6komo0e in base35 is 2Cd8gwy in base40. So the latter can be used as a user's password. Notice that to recover the original input, a hacker will need to know the sequence of bases, or base increments, used and which alphabet was implemented. Repeat this exercise with your name, but this time using a variable base increment as an extra security layer.
- One-to-many maps can be used as part of a brute-force strategy for cracking passwords. Suggest a procedure for doing this.
