Are there any sites that can compress and uncompress private keys? Or any open source code i can borrow?
Bitcoind is giving me pub key compressed.
http://coinb.in/multisig/ takes uncompressed.
Sorry, title is correct, body is wrong. Are there any sites that can compress and uncompress
private public keys?
You need to explain what you are trying to do.
It is unlikely that "uncompressing a public key" will accomplish what you want. Perhaps you have some interesting new use for uncompressed public keys, but most likely you simply misunderstand what a "compressed public key" is.
A public key (uncompressed) is simply an x and y coordinate of a point on a graph. A compressed public key is just the x coordinate. Using the x coordinate you should be able to calculate the y coordinate if you really want it, but I don't understand why that would be useful to you.
Sorry:
I am trying to use
http://coinb.in/multisig/ to create a mulitsig address, using 2 keys from 2 wallets. Eg, blockchain.info and bitcoin-core. However, it requires the public keys to be uncompressed.
Bitcoin-core via the validateaddress <bitcoinaddress> command outputs the public key in compressed form.
www.blockchain.info dump the public key command, also yields the public key in compressed format. Heres one example 0320e1011a724a4817365dd7fcb92bca63de802e1972130d607581a17eb71451fa
In order to use
http://coinb.in/multisig/ I need to uncompress the keys.
