Typeerror: unicode-objects must be encoded before hashing

Looking for a solution on how to solve the error “typeerror: unicode-objects must be encoded before hashing“? Read through the end of this article.

In this article, we will show you how to solve this error, and apart from that, we’ll also provide you with a brief discussion of what typeerror and Python are.

What is this error?

The typeerror: unicode-objects must be encoded before hashing is an error in Python that is usually encountered by developers who are attempting to hash a Unicode string in Python without encoding it first into a byte string.

TypeError and Python

What is typeerror?

Typeerror is a common error in Python that arises when an operation or function is applied to a value of an improper type. This error indicates that the data type of an object isn’t compatible with the operation or function that is being used.

What is Python?

Python is one of the most popular programming languages. It is used for developing a wide range of applications.

In addition to that, Python is a high-level programming language that is usually used by developers nowadays due to its flexibility.

Typeerror: unicode-objects must be encoded before hashing – SOLUTION

Fixing the error “typeerror: unicode-objects must be encoded before hashing” in Python is an easy task. All you have to do is encode the Unicode string into bytes before passing it to the hash function.

Time needed: 2 minutes.

Follow the guide below to solve the error.

  1. Convert the Unicode string to bytes.


    To convert the Unicode string to bytes, use the encode() method.

    Example:

    s_bytes = s_string.encode('utf-8')

  2. Pass bytes to the hash function.


    To do so, use the code:

    import hashlib

    s_hash = hashlib.sha256(s_bytes).hexdigest()

Example Code

import hashlib

s_string = "Hi, ITSourceCoders!"
s_bytes = s_string.encode('utf-8')
s_hash = hashlib.sha256(s_bytes).hexdigest()

print(s_hash)

Output:

c7ab560f1af310048e7a518300b2364fc05312de182511dc50b22d6038c3e535

Tips to avoid getting Typeerrors

The following are some tips to avoid getting type errors in Python.

  1. Avoid using the built-in data types in Python in the wrong way.

    → Make certain that your variables and data structures are using the correct data types.
  1. Always check or confirm the types of your variables.

    → To check the types of your variables, use the type() function. This will allow you to confirm if the type of your variable is appropriate.
  1. Be clear and concise when writing code.

    → Being clear and concise when writing your code can help you avoid typeerrors. It is because it will become easier to understand.
  1. Handle the error by using try-except blocks.

    → Try using the try-except blocks to catch and handle any typeerror that may arise when working with code.
  1. Use the built-in functions of Python if needed.

    → Use built-in functions such as int()str()float(), or bool() if you need to convert a variable to a different type.

Conclusion

In conclusion, the error “typeerror: unicode-objects must be encoded before hashing” in Python can be easily solved by encoding the Unicode string into bytes before passing it to the hash function.
