This code is a modified version of https://github.com/doegox/python-cryptoplus/blob/master/src/CryptoPlus/Hash/pymd5.py by Dinu C. Gherman. It supports python 2 and 3. pymd5 has these methods: - update(arg): Update the md5 object with the string arg. Repeated calls are equivalent to a single call with the concatenation of all the arguments. - digest(): Return the digest of the strings passed to the update() method so far. This may contain non-ASCII characters, including NUL bytes. - hexdigest(): Like digest() except the digest is returned as a string of double length, containing only hexadecimal digits. For example, to obtain the hexdigest of 'Hello World': >>> import pymd5 >>> m = pymd5.md5() >>> m.update(b"Hello World") >>> m.hexdigest() More condensed: >>> pymd5.md5(b"Hello World").hexdigest() Shoud give the same result as: >>> import hashlib >>> hashlib.md5(b"Hello World").hexdigest() N)@Z 0xD76AA478LZ 0xE8C7B756LZ 0x242070DBLZ 0xC1BDCEEELZ 0xF57C0FAFLZ 0x4787C62ALZ 0xA8304613LZ 0xFD469501LZ 0x698098D8LZ 0x8B44F7AFLZ 0xFFFF5BB1LZ 0x895CD7BELZ 0x6B901122LZ 0xFD987193LZ 0xA679438ELZ 0x49B40821LZ 0xF61E2562LZ 0xC040B340LZ 0x265E5A51LZ 0xE9B6C7AALZ 0xD62F105DLZ 0x02441453LZ 0xD8A1E681LZ 0xE7D3FBC8LZ 0x21E1CDE6LZ 0xC33707D6LZ 0xF4D50D87LZ 0x455A14EDLZ 0xA9E3E905LZ 0xFCEFA3F8LZ 0x676F02D9LZ 0x8D2A4C8ALZ 0xFFFA3942LZ 0x8771F681LZ 0x6D9D6122LZ 0xFDE5380CLZ 0xA4BEEA44LZ 0x4BDECFA9LZ 0xF6BB4B60LZ 0xBEBFBC70LZ 0x289B7EC6LZ 0xEAA127FALZ 0xD4EF3085LZ 0x04881D05LZ 0xD9D4D039LZ 0xE6DB99E5LZ 0x1FA27CF8LZ 0xC4AC5665LZ 0xF4292244LZ 0x432AFF97LZ 0xAB9423A7LZ 0xFC93A039LZ 0x655B59C3LZ 0x8F0CCC92LZ 0xFFEFF47DLZ 0x85845DD1LZ 0x6FA87E4FLZ 0xFE2CE6E0LZ 0xA3014314LZ 0x4E0811A1LZ 0xF7537E82LZ 0xBD3AF235LZ 0x2AD7D2BBLZ 0xEB86D391LZ0LZ 0xffffffffLZ0x3FLZ 0x67452301LZ 0xefcdab89LZ 0x98badcfeLZ 0x10325476Ll?i#Egl+_l\u1ivT2Lc Cstt|d}tg|}d}d}||krtjddkrItt||}tt||dd>}tt||dd>}tt||dd>}nc||}t|trXt||}t||dtrlt||dd>}n||dd>}t||dtrt||dd>}n||dd>}t||dtrt||dd>}n||dd>}||B|B|B||<|d}|d}||ks|S) z4Transform a list of characters into a list of longs.rr) intlen long_zerosys version_infolongord isinstancestr) listZimaxZhljiZb0Zb1Zb2Zb3r6usr/lib/python3.10/site-packages/oci_cli/util/pymd5.py_bytelist2longWs6   rcCs||>|d|?BS)z)Rotate x (32 bit) left n bits circularly. r)xnrrr _rotateLeft|srcCs||@||@BSNrryzrrrFr"cCs||@||@BSrrrrrrGr#r$cCs ||A|ASrrrrrrHs r%cCs|||BASrrrrrrIsr&c CsRt}||||||}||}||}|t@}t||}|t@}||}|t@S)zWrapper for call distribution to functions F, G, H and I.

Update the md5 object with the string arg. Repeated calls are equivalent to a single call with the concatenation of all the arguments, i.e. m.update(a); m.update(b) is equivalent to m.update(a+b). The hash is immediately calculated for all full blocks. The final calculation is made in digest().
