the number 3, eg: Bech32 type starting with bc1, eg: Contents, a Bitcoin address is a single-use token. So, to turn this script into an address, you simply apply base58check to the ripemd160 of the SHA256 of the script OP_0 0x14 PubKey Hash except you prepend 0x05 to the script hash instead of 0x00 to denote the address type is a P2SH address. Address validation, if you would like to validate a Bitcoin address in an application, it is advisable to use a method from this thread rather than to just check for string length, allowed characters, or that the address starts with a 1. Also, something encrypted with a private key can be decrypted with the public key, and vice-versa, hence they are asymmetric.

The checksum also allows Bitcoin software to confirm that a 33-character (or shorter) address is in fact valid and isn't simply an address with a missing character. Validation may also be done using open source code available in various languages or with an online validating tool.

Several of the characters inside a Bitcoin address are used as a checksum so that typographical errors can be automatically found and rejected. This is possible because every computer character is represented by an integer value (see ascii and Unicode). The shiny hologram tape used to seal up the paper wallets you see on this site isn't just for good looks. See the dedicated article on address reuse for more details. K is the public key, k is the private key, and, g is a constant called the Generator Point, which for secp256k1 is equal to: 04 79BE667E F9dcbbac 55A06295 CE870B07 029bfcdb 2DCE28D9 59F2815B 16F81798 483ADA77 26A3C465 5DA4fbfc 0E1108A8 FD17B448 A6855419 9C47D08F FB10D4B8.
