What is the output format of SHA256

What is the output format of the SHA256? It is composed by letters and numbers only? And it is case insensitive?

What is the output of SHA256?

SHA-256 is a patented cryptographic hash function that outputs a value that is 256 bits long.

How many bytes is the output of SHA256?

SHA-256 produces a 256-bit (32 bytes) hash value. It's usually represented as a hexadecimal number of 64 digits.

Is SHA256 a binary?

The output-type of a SHA256 (or many other hash algorithms) is raw binary. So you can use this binary value to convert it to any format you want, i.e. decimal.

As with most (all?) crypto hashes, the output of SHA-256 is binary data. How that binary data is encoded in a text format is up to you. For example, you could encode it as hex, or base64.
