Base module has the below explanation but I can't exactly understand how to convert my message. I guess that I need to convert the message first to something else and then to base And to decode the base58 message, again, a conversion to something else is needed and from there to text, right?

It is similar to Base64 but has been modified to avoid both non-alphanumeric characters and letters which might look ambiguous when printed.
It is therefore designed for human users who manually enter the data, copying from some visual source, but also allows easy copy and paste because a double-click will usually select the whole string.
The Base58 encoding format is designed for use in Bitcoin and is used in many other cryptocurrencies. It offers a balance between compact performance, readability, definition and error prevention. Base58 is a subset of Base64 that uses lowercase and uppercase letters and numbers, but without some characters that are often mistaken for each other and can be identical in some fonts.
Or, simply put, it is a set of uppercase and uppercase letters and numbers without the four 0, O, L, I mentioned above. In contrast to Base64, the digits of the encoding do not line up well with byte boundaries of the original data.
For this reason, the method is well-suited to encode large integers, but not designed to encode longer portions of binary data. A variant, Base56, excludes 1 one and o lowercase o compared to Base Base58Check is a Base58 encoding format that unambiguously encodes the type of data in the first few characters and includes an error detection code in the last few characters.
With Base58, private key can be converted to a public key, but a public key cannot be converted to a private key. The bitcoin address is not really a public key, but its hash. Bitcoin address is not presented in hexadecimal form as secret and public keys. This is because for him, Bitcoin uses a "compressed" format, known as base58check. Bitcoin Base58 suggests that it uses 58 different letters and numbers zero, O, l and I are omitted, as they are too easily confused with each other. Base58 is a number with a base similar to the usual for us binary base 2decimal base 10 or hexadecimal base 16 representation.
Well, the suffix check in the description of the format means that before the translation of a number in base58 it still adds a four-byte "check sum". All bitcoin libraries which we will talk about later make a transfer to base58check automatically, so you do not have to program it specifically.
Four bytes of checksum are added to the end of the encoded data. The checksum is obtained by hashing the encoded data and can therefore be used to detect and prevent transcription and typo errors. The software will calculate the checksum of the data when decoding and compare it with the checksum of the code. The mismatch will indicate an error and the Base58Check data will be invalid. For example, such a check prevents the possibility of sending funds to a non-existent Bitcoin address and thus losing funds.
To convert data numeric to Base58Check format, you must first add a prefix to The data, called a "version byte", which is used to determine the type of data to be encoded. For example, in the case of a Bitcoin address, the prefix is 0 0x00 in the hex systemwhile the prefix for the private key is 0x80 in the hex system. Next, we compute a checksum of the "double-SHA", in the sense that the used hash algorithm is SHA twice on the previous result prefix and data. These four bytes serve as the error-checking code, or checksum.
This checksum is then added to the end of the line. The result consists of three elements: prefix, data, and checksum. This result is encoded using the Base58 alphabet described earlier.

An example of a hexadecimal number is 3BF2. Computer science applications can use hexadecimal for binary coding in computing and digital electronics. While computers work with binary data, it can be difficult for humans to work with a large number of digits. Humans typically use a base 10 system, while for computer applications it is easier to work with hexadecimal than decimal. As hex saves space either paper space or screen spaceyou can more efficiently use hex instead of a large number of ones and zeros.
You can also go from hex back to binary bits if needed. For example A is Hex numbers represent large numbers compactly and are used in programming as computers use bytes as a unit of information.
In hex you need two digits where you need 8 binary digits to represent a byte. Hexadecimal is also used in the Red-Green-Blue color system in computers. Red, green, and blue are each represented by a byte that is two hex digits.

Base58 is a more human-friendly encoding than Base64 because some similar characters are omitted to avoid confusion when printed.
The characters used in Base58 encoding are as the following. The characters used in Base58 encoding can be divided into three groups; i.
Bitcoin is a cryptocurrency which is a digital asset used as an alternative to money on the internet which is considerably safe, secure, and anonymous abbreviated as BTC.
You can get Bitcoin by either mining it using Bitcoin mining hardware or buying existing Bitcoin directly from a cryptocurrency exchange platform. There are only 21 million Bitcoins in total.
The more Bitcoins are mined, the more difficult mining will be. The following is an example of a Bitcoin address which is comprised of the characters in Base58 encoding. A Bitcoin address can be accessed using the corresponding private key which is Base58 encoded as well.
The satoshi is the smallest unit of Bitcoin named after the person who created Bitcoin, Satoshi Nakamoto. However, the identity of Satoshi Nakamoto has still been unknown ever since the Bitcoin currency has been created. However, the addresses of altcoins may not implement Base58 encoding.

Base10 Decimal :. Base16 Hexadecimal :. So in everyday life, we are used to working with base10 numbers using the digits The more characters you have in your basethe less of them you will need to use to represent big numbers.
Because 58 is the number of characters you are left with when you use all the characters in the alphanumeric alphabet 62but remove all the easily mistakable characters like 0Ol and I. To convert an integer base10 to base58, you use the modulus 1 function to work out which characters you need to represent the original number. Basically, you keep dividing your number by 58, taking the remainder at each step of the way to get the next character indexfinishing when there are no remainders left.
To convert a base58 number in to base10, you take each character index and multiply it with how many 58s that position in the number represents. Base58 is used when you want to convert commonly used things in bitcoin in to an easier-to-share format. For example:. Bitcoin Base58 also converts every byte of zeros 0x00 at the start of a number to a 1. You see, putting zeros at the start of a number does not increase the size of the number e.
