It would be useful to know this because I have made a 64 character hex private key by hand and generated the address without storing the key in WIF format. I don’t want to go online, input the hex key and have it rejected.
Of course I could try it out with a small amount in a sloppy wallet, but it would be easier for someone to tell me.
WIF stands for "Wallet Interchange Format" - the standard way for importing/exporting bitcoin private keys. Yes, it is possible to keep private keys in HEX, BASE64 and 100500 other formats. But why should anyone implement them? – amaclin – 2014-08-28T09:14:00.180
Why? Because I made a random 64 character hex key not using a computer. And offline, I found the B58Check address which that key makes and then paid some Bitcoin into it. I now want to redeem the money. – Peter – 2014-08-28T09:47:23.660
You can use https://brainwallet.github.io/ (1) set "Get Address From" to "Secret Exponent" (2) type your hex key into the field "Secret Exponent" (3) get your private key in WIF format in the field "Private Key"
