I've seen posts on how to do it and I've read the wiki on what it is, however these explanations are too complex. Can someone explain what it is and why it's called Base58Check encoding? Are addresses generated without going over those steps still valid in Bitcoin?
This is the explanation provided by the original bitcoind client in base58.h
// Why base-58 instead of standard base-64 encoding? // - Don't want 0OIl characters that look the same in some fonts and // could be used to create visually identical looking account numbers. // - A string with non-alphanumeric characters is not as easily accepted as an account number. // - E-mail usually won't line-break if there's no punctuation to break at. // - Doubleclicking selects the whole number as one word if it's all alphanumeric.
To further this question, what do npm packages like bs58check do exactly? The description is as so
A straight forward implementation of base58check extending upon bs58.
