 ===== Pay-to-script-hash addresses

-((("addresses, bitcoin","encrypting with P2SH")))((("Pay-to-script-hash (P2SH)","addresses")))Another important part of the P2SH feature is the ability to encode a script hash as an address, as defined in BIP0013. P2SH addresses are Base58Check encodings of the 20-byte hash of a script, just like bitcoin addresses are Base58Check encodings of the 20-byte hash of a public key. P2SH addresses use the version prefix "5", which results in Base58Check encoded addresses that start with a "3". For example, Mohammed's complex script, hashed and Base58Check-encoded as P2SH address becomes +39RF6JqABiHdYHkfChV6USGMe6Nsr66Gzw+. Now, Mohammed can give this "address" to his customers and they can use almost any bitcoin wallet to make a simple payment, as if it were a bitcoin address. The 3 prefix gives them a hint that this is a special type of address, one corresponding to a script instead of a public key, but otherwise it works in exactly the same way as a payment to a bitcoin address.

 P2SH addresses hide all of the complexity, so that the person making a payment does not see the script.
