We also use the decode() method to convert the resulting bytes object to a string in ASCII format.

Formatters (like Base64 and Utf8) are interfaces between this WordArray format, and strings, which may contain data encoded in any format. This is because hexdigest() returns a hex-encoded string, whereas we want to produce a Base64-encoded string. var words ('SGVsbG8sIFdvcmxkIQ') var base64 (words) // 'Hello, World' The WordArray is CryptoJS's format-independent representation of data.

Note that we are encoding the digest() of the sha1_hash object, instead of its hexdigest(). Sha1_hash = hashlib.sha1(di_plainTextDigest.encode())īase64_hash = base64.b64encode(sha1_hash.digest()).decode('ascii')

Here is the Python code that should produce the same result as the JavaScript code: import hashlibĭi_plainTextDigest = 'your plaintext digest' To replicate the JavaScript code in Python, you can skip the hex encoding step and directly encode the SHA1 hash of di_plainTextDigest in Base64. It generates longer strings but they cannot be decrypted without the password. If you are looking for a secure encryption algorithm that would require a secret passphrase for decrypting the encrypted text, go with AES. Note: The naming of these functions reference old Unix commands for converting binary to ASCII (btoa) and ASCII to binary (atob). In the JavaScript code, the di_plainTextDigest is encoded using the Base64 format, whereas in your Python code, you are encoding the SHA1 hash of di_plainTextDigest as a hex string before encoding it in Base64. The obvious downside is that Base64 is encoding (not encryption) and the Base64 strings can be easily decoded. Encoding and Decoding Strings with Base64 btoa () and atob () are two Base64 helper functions that are a core part of the HTML specification and available in all modern browsers. However, the difference between your Python code and the JavaScript code is in the encoding format used.

To replicate the functionality of the JavaScript code in Python, you can use the hashlib and base64 modules as you have attempted to do.
