![]() ![]() Then the last line becomes: return hash.digest ().encode ( 'base64' ). MAC keys and other options should be set via -macopt parameter. Python, get base64-encoded MD5 hash of an image object 14,750 Solution 1 I was able to make it work by using digest () instead of hexdigest (). MD5 hash generates 128-bit long output so out of 128 bits we will take 43 bits to generate a tiny URL of 7 characters. The most popular MAC algorithm is HMAC (hash-based MAC ), but there are other MAC algorithms which are not based on hash, for instance gost-mac algorithm, supported by ccgost engine. MD5 Encoding: MD5 also gives base62 output but the MD5 hash gives a lengthy output which is more than 7 characters. The MD5 hash function is provided via the hashlib module which is provided by default with Python. Python provides a function in order to calculate MD5 values and work with them easily. The MD5 is a non-reversible and one-way function. mac alg:create MAC (keyed Message Authentication Code). Hashlib is an open-source python library used for encoding and it contains most of the popular hashing algorithms used by big tech firms for security purposes. MD5 is a hashing algorithm that is used to create unique value for a given data or string. hmac key:create a hashed MAC using "key". Where the key authentication is explained as follow: ![]() (stdin)= 01433efd5f16327ea4b31144572c67f6įor more information u can refer to the openssl library Thanks alot for ur feedback and answers, I found a way to use a secret key authentication called HMAC (Hashed Message Authentication Code)Īnd it echo -n 'value' | openssl dgst -md5 -hmac 'key' I cannot use any C# or php or any other programing tool except python and standard linux libraries. I also tried to use Debian standard library MD5sum but still I cannot figure how to change the key used to creat the hash.Īppreciate if any one has any ideas, I cannot use any online tool because I want to include this MD5 hash in my python program or at least using standard Debian Library. In the article they even state how it takes only 6 characters of base 64 to yield 68.7 billion possibilities. Encoding those 1's and 0's with base 64 considerably shortens the number of characters needed to represent the hash. Hash.update("this is the text to be hashed") Naively using those 1's and 0's in your url makes it unnecessarily long. I already digged through the internet and I can find an MD5 library in python but it doest have the option of changing the key used Where the idea is to have two machines exchanging messages and applying security check through the MD5 hash of the messages using a secret key.Īnd no one should know this specific key.Īnd I am using python as a programing language. I am trying to Hash a txt file using MD5 Algorithm, the problem is I want to hash the text file using a special key for a security reason. ![]()
