Because there are 26 letters (213) in the basic Latin alphabet, ROT13 is its own inverse; that is, to undo ROT13, the same algorithm is applied, so the same action can be used for encoding and decoding. The algorithm provides virtually no cryptographic security, and is often cited as a canonical example of weak encryption.[1]
ROT-47 is an extension of the ROT-13 encryption method that provides a greater level of text obfuscation. Unlike ROT-13, which operates only on alphabetical characters, ROT-47 applies its encryption to a wider range of ASCII characters, including letters, numbers, and symbols.
The ROT-47 algorithm works by shifting each character by 47 positions in the ASCII table. This means that every character, regardless of its type, is substituted with another character 47 places ahead. The rotation wraps around the ASCII table, allowing for the encryption of a broader set of characters.
Although ROT-47 provides a higher degree of obfuscation compared to ROT-13, it is still a relatively weak encryption method and is not suitable for secure communication or sensitive data protection. It is primarily used as a form of simple encoding to prevent casual reading or automated scanning from recognizing the text's content.
ROT13 is easy to translate without any tools. If you think might be looking at a piece of ROT13 code, all you need to do is to write the letters A-M on a piece of paper, and the letters N to Z below them. You can then substitute the letters accordingly, so if the cipher text has a letter A, the plain text is N and vice versa.
While it should never be used for serious encryption, ROT13 still has a lot to offer. Because it has no key, it allows you to share encrypted text with others who can then easily decipher them making it useful for hiding information such as hints or spoilers until the reader is ready to see them.

A simple, intuitive web app for analysing and decoding data without having to deal with complex tools or programming languages. CyberChef encourages both technical and non-technical people to explore data formats, encryption and compression.
Is there any simple algorithm that can do this without generating stuff like keys or additional passwords? I understand that keys and passwords are a must for encryption and decryption, but my scenario does not require it.
The ROT47 substitution cipher is a very simple form of encryption that works simply by rotating the ASCII characters from '!" to '' by 47 positions (hence its name). Therefore, spaces in the plain text remain unchanged, but other characters are replaced with their rotated equivalents.
The Caesar cipher or shift cipher method uses a simple substitution encryption. This means that every character is substituted by another character according to a specific system. The substitution character is determined by rotating the alfabet. For example, the wel known and mostly used ROT13 method shifts the alphabet with 13 positions, this results in: A=>N, B=>O, ...,Y=>L and Z=>M. Every other shift is also possible. In the exceptional case of the ROT13 method with 13 rotations the same key can be used for encryption and decryption. This does not work for the other shifts, keep this in mind.
A variation to the standard Caesar cipher uses a key word or alphabet key to alter the alphabet. The characters of the key word are added to the beginning of the substitution alphabet and removed from their original location. Needles to say, every character is still used only once in the alphabet, although they may be used more than once in the key word.
ROT47 cipher online encoder and decoder. Encrypt and decrypt any cipher created in a ROT47 cipher. You can use any shift and additionally a key for more precise text encoding.
ROT47 cipher is a simple shift, substitution cipher, replacing each ASCII character in the range 33-126 with a character located 47 positions further, but not further than up to 126 positions, with the direction of change being preserved. Using our encoder you can both encode and decode each text with the ROT47 cipher. By default, the ROT47 cipher does not contain the encryption key (except for shifting the alphabet by 47 positions), so select whether you want to use it. Then select the alphabet offset (for ROT47 leave the default). If you select the option to show all offsets then as a result of encoding / decoding you will get a cipher with each shift from 1 to 47. You can also use the key generator.
Let's say you've a string (you obtained from somewhere, maybe a boot2root machine, ctf, etc.), you know it's encoded (isn't a hash and is not encrypted) but just can't figure out the encoding mechanism used? No worries, this script will try and decode it in most used encoding mechanisms (i.e. base64, rot47, atbash, etc.)
Using this handy VBS tool, you can convert your VBScript into an obfuscated VBS source code, without compromising/altering the scripting functionalities and the VBScript keywords. This Free VBScript Obfuscator works by converting each character in your VBS source code into a much obfuscated format. Then these obfuscated letters are combined at runtime and be executed via the Execute function.
However, sophicated software engineer knows how to reverse engineer the obfuscated VBScript source code within a few minutes. This should not be trusted in hiding any sensitive information inside your VBScript source code. However, you can use this tool if you do not want people read the VBS source at an easy glance and modify it.
Combined with ROT47, the VBScript obfuscator can be quite powerful. The source code of ROT47 VBScript Obfuscator. For example, the original VBS is:MsgBox "Hello, @justyy"and it can be obfuscated to:Function l(str):Dim i,j,k,r:j=Len(str):r="":For i=1 to j:k=Asc(Mid(str,i,1)):If k>=33 And k sample-obfuscated.vbsThe ROT47 is a Caesar cipher by 47 chars. If you apply rot47 on the same string twice, you will get its original version. The VBScript source code for ROT47 VBScript obfuscator is maintained in github and the following is the core implementation:Function Rot47(str) Dim i, j, k, r j = Len(str) r = "" For i = 1 to j k = Asc(Mid(str, i, 1)) If k >= 33 And k
- Please be aware that I do not take responsibility for the loss of your VBScript source code.
- You should always keep a copy of your original VBScript source code.
- Most of the time, the obfuscated VBScript still works, but not 100% (no guaretee) will work.
- Please kindly report bugs to [email protected]
- This VBScript tool is maintained and will be updated on regular basisc. Please consider a donation, thanks!
We could not find any login page or any other useful functionally on the website, so we decided to enumerate the hidden files and directories that might be present in the website. For this, we used the popular web application enumeration tool dirb. The command used and the output can be seen in the following screenshot:
We can understand from the above results that rot47 is actually a cipher that replaces characters within ASCII range with the character 47 places after it in the ASCII table. It indicates that this cipher must have been used somewhere in the website. We checked the login credentials given on the website and found that all the credentials were given in plaintext except one.
If you refer to my previous post, a hash can be cracked using hashcat either by brute force or dictionary. However, it is not a 100% guarantee that the hash can be cracked using the hashcat. For this task, the author suggested using a brute-forcing. However, it is impossible as the permutation is too large and it will take more than a day. The only way to do that is to decrypt it using online tools such as md5decrypt. This is because the hashed text has been stored in their database.
This task is easy. Just download any sound or wave analyzer tool such as aducity. For this task, I going to use wavepad. Simply open the downloaded wave file and open it up in TFFT (Tool > TFFT). A message will be revealed.
The name "ROT13" originated on Usenet in the early 1980s, and the method has become a de facto standard. Although a Caesar cipher, a method of encryption thousands of years old, ROT13 provides no real cryptographic security and is not used for such; in fact it is often used as the canonical example of weak encryption. Because ROT13 scrambles only letters, more complex schemes have been proposed to handle numbers and punctuation, or arbitrary binary data.
Obviously, encryption schemes which have been proven to be vulnerable shouldn't be used, so sometimes it's more clear than others, but what I'm struggling with is how I know where the conventional wisdom does and doesn't apply.
An example of a mechanism would be AES, or SHA-1, or for your example, SSH.
An example of an implementation/configuration would be which port SSH is listening on, or which encryption algorithm you've chosen to encrypt your application's data. An example of data is a private key, or a password.
An implementation may or may not be obscured. Generally, it neither hurts nor helps security materially when you do this. You may see fewer port scans identifying your SSH port, or you may be able to hide the encryption algorithm used for a particular ciphertext, but for a secure mechanism without the secret data, it should not matter. The mechanism should still be unexploitable. There's a argument that there's a marginal security benefit here, and a marginal harm to usability. Your milage may vary.
