Ethereum: RIPMD160 (Sha256 (Publickey)) – Where do I go wrong?
When you start your journey to understand Ethereum, you are likely to feel the concept of encryption keys and their role in securing transactions. When it comes to creating and verifying signatures with the help of Ethereum’s Ripemd160 HAH, there are several common pitfalls that can lead to errors.
In this article, we explore Ethereum’s Ripemd160 (Sha256 (Publickey)) formula and explore where you may go wrong.
Understanding the formula
The RIPMD160-HHH function is a one-way encryption algorithm that takes a big bet (public key) as an argument and produces a fixed size (signature). The basic formula is:
RIPMD160 (Sha256 (Publickey)) = Sha256 (Publickey) + NONCE
If the NONCE is the nonces (initial vectors) used in the SHA-256 Distance Process.
Topic
Now let’s explore where you may go wrong. Here are a few questions:
- Public Key Form : Make sure your public key is in the correct form of Ethereum. The “publickey” argument should be a hexadecimal string with at least 64 characters (32 syllables) and not a cushion.
- Sha-256 Output : Make sure you use the public key’s Sha-256 output to the Ripemd160-HHH function. Make sure that the Sha-256 output is not cut or edited in any way.
- Ripemd160 algorithm version
: The Ethereum Ripemd160 algorithm uses the SHA-256 algorithm. If you use another version, make sure it is compatible with the requirements of Ethereum.

Example of use
Let’s look at the example where you may go wrong, look at:
Suppose you have a public key 0x1234567890ABCDEF and you want to create a signature using Ethereum Ripemd160 (Sha256 (Publickey))). However, if your neck is incorrectly formatted or if you do not use the public key's SHA-256 output as expected, you may face errors.
Javascript
Const Ripemd160 = Crypto.Createhash (‘RIPMD160’);
Const Sha256 = Crypto.Createhash (‘Sha256’);
// Start nonce correctly
Const nonce = 0x1234567890ABCDEF;
// Convert the public key into a hexadecimal string
Const publickey = ‘0x1234567890ABCDEF’;
// Use the SHA-256 output as a result for RIPMD160
Ripemd160.update (Sha256.update (publickey, ‘UTF8’));
Let the Ripemd160Signature be;
if (Ripemd160.digest (). Tatring (‘hex’)! == Sha256.digest (). Tatring (‘Hex’)) {
Console.error (‘creating an error signature’);
}

conclusion
When using the Ethereum Ripemd160 (Sha256 (Publickey)) formula, make sure that you follow the best practices of the public key form, Sha-256, algorithm version compatibility and non-platform. By doing this, you are on a good way to create and verify signatures in Ethereum-based applications.
