   alternatives methods?
            Asked 2021-Mar-11 at 17:05

   I can't access this URL, Is this service stopped?

            I want to compress a file using dead.edwards/packer/ with a Base62 encode. What are the alternative methods you know guys?

            Thanks for helping :)

            Designing a URL Shortening service like TinyURL
            Asked 2020-Apr-22 at 12:55

            I'm reading an online document that explains how to design a url shortening service. The website is .

            In the section, Encoding actual URL, they said -> "We can compute a unique hash (e.g., MD5 or SHA256, etc.) of the given URL. The hash can then be encoded for displaying. This encoding could be base36 ([a-z ,0-9]) or base62 ([A-Z, a-z, 0-9]) and if we add ‘+’ and ‘/’ we can use Base64 encoding. A reasonable question would be, what should be the length of the short key? 6, 8, or 10 characters."

            "If we use the MD5 algorithm as our hash function, it’ll produce a 128-bit hash value. After base64 encoding, we’ll get a string having more than 21 characters (since each base64 character encodes 6 bits of the hash value).Since we only have space for 8 characters per short key, how will we choose our key then? We can take the first 6 (or 8) letters for the key. This could result in key duplication, to resolve that, we can choose some other characters out of the encoding string or swap some characters."

            I used online MD5 hash generator ( and Base64 encoder ( to verify the above. I used "" as the input string for MD5 hash and output is 1B03577ED104F16AADC00A639D33CB44 . Then I Base64 encoded it and got MUIwMzU3N0VEMTA0RjE2QUFEQzAwQTYzOUQzM0NCNDQ= with UTF-8 destination charset and Unix newline seperator.

            Can anyone explain if I'm doing it correctly? I see the number of characters are way more than 21.

            The problem is that you are using the output of MD5 as a string of hexadecimal digits, and then base64 encoding that string. There's no reason to base64 encode that string - base64 encoding is intended for binary data. What you probably wanted to do is base64 the actual 128-bit binary value of the MD5 hash. Here is some Python code that does what I think you are trying to do:



            recursively encrypt property which ends with 'id' or '_id'
            Asked 2020-Apr-12 at 09:01

            I want to encrypt and decrypt recursively any key which ends with id or _id.

            It should loop through all the key inside passed array or object or array of objects to search for the key and encrypt it. Finally it will return encrypted data.

            I tried below function, but it's not working.



            Answered 2020-Apr-12 at 08:38

            For data that is not Array or object and ends in id or _id you are recursively calling encryptor

            You should end the recursion for that branch



            How to fix the code for base62 encoding with Python3?
            Asked 2019-Oct-07 at 21:44

            I am creating a python script for base62 encoding. However, for some reason, my code doesn't produce the correct answer. Correct answer is LpuPe81bc2w, but i get LpuPe81bc0w. If you can review my code and see if I can do any different. Please let me know. I can't use pybase62.

            I really want to know why my code doesn't work because I want to understand fundamental. Preferably

            NO PyBASE62 and I am a beginner.

            Encoding UUID to Base62 (not Base64) in Java
            Asked 2019-Aug-21 at 15:49

            I'm trying to shorten UUID values (stored in DB as UUID, not string) to be embedded in URLs. I'm aware of Base64 for URL, but trying to see if I can make it without dash and underscore characters. So I would like to convert UUID to base62. After a lot of googling I found:

            1. There's not a standard for this (something like RFC2045), am I right?

            2. Most importantly there's no proper implementation for it. I found a lot of snippets on how to do it, but with some sort of note that "this is a naive implementation" or something. Is there a proper implementation (I don't mind the exact interpretation how the mapping should be done as long as it's done properly)?

            3. There are some base classes in Apache Commons Codec and Guava which are extended for Base32 and Base64, but I didn't find it easy to extend it for Base62. Is it even possible to do it (considering the fact that the mapping is fundamentally different)?



            Answered 2019-Aug-21 at 15:49

            You might want to try this library:

            The FriendlyID library converts a given UUID (with 36 characters) to a URL-friendly ID (a "FriendlyID") which is based on Base62 (with a maximum of 22 characters), as in the example below:

            My Docker container builds fine on OSX:



            Answered 2018-Mar-29 at 19:04

            To solve this problem, I followed @MazelTov's advice and built the containers on my local OSX development machine, then published the images to Docker Cloud, then pulled those images down onto and ran the images from my production server (AWS EC2).

            Install Dependencies

            I'll try and outline the steps I followed below in case they help others. Please note these steps require you to have docker and docker-compose installed on your development and production machines. I used the gui installer to install Docker for Mac.

            Build Images

            After writing a Dockerfile and docker-compose.yml file, you can build your images with docker-compose up --build.

            Upload Images to Docker Cloud

            Once the images are built, you can upload them to Docker Cloud with the following steps. First, create an account on Docker Cloud.

            Then store your Docker Cloud username in an environment variable (so your ~/.bash_profile should contain export DOCKER_ID_USER='yaledhlab' (use your username though).

            Next login to your account from your developer machine:

            docker login

            Once you're logged in, list your docker images:

            docker ps

            This will display something like:



            Reverse a Base 62 String of length 3 back to an Integer
            Asked 2018-Mar-21 at 12:28

            I have obtained following code to convert an Integer to a Base62 character of length 3. Is there a way I could reverse this to obtain back the initial Integer?

            Example: Following code converts the Integer 238328 to "zzz" which is what I want. Is there a way I could use back "zzz" and get back the Integer 238328?

            Based on the original algorithm you need to iterate through each character of the encoded string, find the location of that character within the alphabet, and calculate the new result.
