How do I create a Bitcoin seed phrase?

Generating a seed phrase is a crucial process in the realm of cryptocurrency. It begins with the creation of random data, which is referred to as entropy. This entropy serves as the foundation for the seed phrase.

Once the entropy is generated, it undergoes a specific process to ensure its integrity. This involves passing the entropy through a hashing function, specifically SHA256. SHA256 is a widely-used cryptographic hash function that converts an input of arbitrary length into a fixed-length string of characters, known as a checksum.

The checksum generated by SHA256 is an essential part of the seed phrase creation process. It provides a unique identifier for the entropy, ensuring that any changes to the entropy will be detectable.

Part of the checksum is then incorporated into the random data, creating a hybrid of entropy and checksum. This hybrid forms the basis of the seed phrase, combining randomness with a level of verification.
