Code:
echo -n "Message" | sha256sum
Don't forget the "-n" otherwise you will hash your message including a newline.

I am not sure about tails, but under Ubuntu you can just use

If you're using Windows and you'd rather not have to install any additional software, there's a certutil command available to calculate hashes (among other things).
To calculate a hash, do certutil -hashfile filename algorithm
For example, certutil -hashfile image.png SHA256
The available hash algorithms are MD2, MD4, MD5, SHA1, SHA256, SHA384, and SHA512.

You can use OpenSSL's hashing command. Or you can write your bytes to a file (with a hex editor or something) and hash the file using sha256sum which comes standard in most linux distributions.

Hello guys,
Do you know any SHA-256 binary hash calculator, like this online one:
https://cryptii.com/hash-function
The goal is to create my own seed from 256 bits generate with a dice, then to the binary sha-256 hash in order to find the last 8 bits (checksum) for my seed.
For obvious security reasons, I want to use a old, offline computer using tails live-cd.
Thanks,
