使用方法
Generate strings
Set the length and count, choose which character sets to include and optionally remove characters that look alike.

常见问题
Why exclude ambiguous characters?
Characters such as I, l, 1, O, 0 and o are easy to confuse when read aloud or typed from paper.
Is the output safe for passwords?
It uses cryptographically strong randomness, but check the length and character sets required by your security policy.
