What is the length of a hashed string with SHA512?

Question

Is the length of a string hashed with sha512 always the same?

If so, what is it?

Answer 1

As the name implies, it's 512 bits, that is 64 bytes.

But that's the hash, maybe you're wondering about a specific representation of that hash in string, as is commonly used, then it depends of the given representation.

If you write the hash in hexa, then it will be 128 characters.

If you write the hash in base64, then it will be 86 bytes (or 88 with padding).
