I need to know what character will the SHA1 will generate for me?
Is it possible to know the characterset of the SHA1? Or if it's configurable, what's the default characterset of it?
Thank you.

In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographically broken but still widely used hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as 40 hexadecimal digits.
The hash size for the SHA1 algorithm is 160 bits.
SHA-1 Keys SHA-1 also referred to as the Secure Hash Algorithm. It is a cryptographic hash function that will take input and it produces a 160-bit hash value. This generated hash value is known as a message digest. This generated hash value is then rendered in a hexadecimal format number which is 40 digits long.
SHA-1 is a hash function designed by the N.S.A. ("SHA" = "Secure Hash Algorithm"). It returns a 160-bit hexadecimal string which is 40 characters long. It was used for secure encryption from 1996 to 2010, largely as a replacement for MD5, but now it is used mostly for data integrity.
SHA-1 doesn't generate text, it generates a binary hash (like most digests), so it doesn't have a charset (or care about the input's charset for that matter).
You can represent it as text (a string representation of the hex value, and base64 are popular) if you want, especially if you need to transfer it over the network or display it to users. That encoding is up to you.

I'm fairly sure it's just binary data rather than any character encoding. You could then encode that in Base64 if you like.
