Does anyone know of a python/C program to input binary or decimal (or both) and output WIF private key?

Thanks, I want something that I can run totally offline, readme says: * Relies on centralized service (blockchain.info) for blockchain operations, although operations do have backups (eligius, blockr.io) Also, not sure if I see the command to take one or both binary or decimal to WIF, I do see these instructions: ### Listing of main commands: * privkey_to_pubkey : (privkey) -> pubkey * privtopub : (privkey) -> pubkey * pubkey_to_address : (pubkey) -> address * pubtoaddr : (pubkey) -> address * privkey_to_address : (privkey) -> address * privtoaddr : (privkey) -> address but nothing for private key in binary or decimal to WIF. There has to be a simple code to do this somewhere. (yeah, I know its not that simple)

Thanks, I want something that I can run totally offline, readme says: * Relies on centralized service (blockchain.info) for blockchain operations, although operations do have backups (eligius, blockr.io) It can be run offline. Just that if you want to do anything involving the network (e.g. send transactions), then you need to be connected to the internet (duh). Also, not sure if I see the command to take one or both binary or decimal to WIF, I do see these instructions:
### Listing of main commands:
* privkey_to_pubkey : (privkey) -> pubkey * privtopub : (privkey) -> pubkey * pubkey_to_address : (pubkey) -> address * pubtoaddr : (pubkey) -> address * privkey_to_address : (privkey) -> address * privtoaddr : (privkey) -> address
but nothing for private key in binary or decimal to WIF.
There has to be a simple code to do this somewhere. (yeah, I know its not that simple)
It does, the commands are encode_privkey and decode_privkey. Look at https://github.com/vbuterin/pybitcointools/blob/master/bitcoin/main.py#L222 for some reference.

Thank You
Check basic-blockchain-programminghttps://github.com/keeshux/basic-blockchain-programming/blob/master/ex-ec-keypair.c uint8_t priv_bytes[32] = { 0x16, 0x26, 0x07, 0x83, 0xe4, 0x0b, 0x16, 0x73, 0x16, 0x73, 0x62, 0x2a, 0xc8, 0xa5, 0xb0, 0x45, 0xfc, 0x3e, 0xa4, 0xaf, 0x70, 0xf7, 0x27, 0xf3, 0xf9, 0xe9, 0x2b, 0xdd, 0x3a, 0x1d, 0xdc, 0x42 };
priv_bytes is exactly what you wanted, your variable of 256 bits

OK, 0.2000 BTC for first person to help me with simple answer.
Reply here that you sent me PM so everyone can see who was first in line, then when you confirm you are first to respond, PM me the solution. If you are 2nd in line, do not send me the solution until I PM you that #1 solution did not work. (I dont want to pay 0.2 * 100 people for an easy answer). If it does not wot work, I will communicate with #1 to troubleshoot my typing errors before asking #2 reply to send the solution.
I am at work and I will try to check this frequently throughout the day, but at certain times it may be an hour or so between me checking for responses.
I have bitcointools installed on an ubuntu server and running the examples in the README.txt work with no problems.
I need some help with the exact syntax of the commands:
I need to know EXACTLY what to replace the XXXXX with and any formatting to input 256 1&0's to get output WIF private keys.
root@ubuntu-server:/home/user/bitcointools/pybitcointools-master/bitcoin# pybtctool XXXXXXXX 101010101010....1010101010101010
Output WIF private key
Thanks!!

see the program https://github.com/keeshux/basic-blockchain-programming/blob/master/ex-wif.cjust compile it and put your private key in hexadecimal to the priv_bytes variable no need to pay me EDIT: compile it like this gcc ex-wif.c -lcrypto -lssl -ldl -o wif then run the wif program: ./wif and u get your wif key

Great, thanks! I am working thru the numbers to make sure I have it correct, I am comparing to the numbers calculated in this thread https://bitcointalk.org/index.php?topic=944596.msg10342157#msg10342157to get the hex, (I know this is probably the hard way), In python I am converting binary to decimal, then to get hex I just use hex(decimal), and I get: 288f39bbfd36da5a12d162cb1897c902288b39bb36da5a12d162cb1897c9023d (same as coin flip thread) So when I edit my ex-wif.c file, I need to replace all the: 0x16, 0x26, 0x07, 0x83, 0xe4, 0x0b, 0x16, 0x73, 0x16, 0x73, 0x62, 0x2a, 0xc8, 0xa5, 0xb0, 0x45, 0xfc, 0x3e, 0xa4, 0xaf, 0x70, 0xf7, 0x27, 0xf3, 0xf9, 0xe9, 0x2b, 0xdd, 0x3a, 0x1d, 0xdc, 0x42 with 288f39bbfd36da5a12d162cb1897c902288b39bb36da5a12d162cb1897c9023d But that will create a problem, not the right format. So I enter this: 0x28, 0x8f, 0x39, 0xbb, 0xfd, 0x36, 0xda, 0x5a, 0x12, 0xd1, 0x62, 0xcb, 0x18, 0x97, 0xc9, 0x02, 0x28, 0x8b, 0x39, 0xbb, 0x36, 0xda, 0x5a, 0x12, 0xd1, 0x62, 0xcb, 0x18, 0x97, 0xc9, 0x02, 0x3d Compile and execute ./wif But I get this: cNwYW8cjd5eywJeSzorEpw5uEfEFdRtqEo55MEsiPiizv4Dk4mNr Instead of the answer in the coin flip thread (and when I tried to import private key, core said invalid private key encoding) I guess I converted long string wrong?. Also, Is there an easy way to change this line (unit8_t) so I can just add in the HEX long string?? uint8_t priv_bytes[32] = { Or is there an easy way to convert this: 288f39bbfd36da5a12d162cb1897c902288b39bb36da5a12d162cb1897c9023d to 0x28, 0x8f, 0x39, 0xbb, 0xfd, 0x36, 0xda, 0x5a, 0x12, 0xd1, 0x62, 0xcb, 0x18, 0x97, 0xc9, 0x02, 0x28, 0x8b, 0x39, 0xbb, 0x36, 0xda, 0x5a, 0x12, 0xd1, 0x62, 0xcb, 0x18, 0x97, 0xc9, 0x02, 0x3d Thanks!

That is because it is doing it for testnet. You need to change the line to Also, if you want the uncompressed key, you need to comment out and change to

Thanks, I am still missing something:
Here is the result: WIF : KxaZ3DctC1ximsBBcQ37TcaqcRvqxyo9AkvcEpRCtc4zfnD9YXcQ should be: 5J89cr5WGdvQWeeekN5ZGzuXVsWREbAYku6MDeUgrJTjX1ZHhCX
Here is my ex-wif.c : include "common.h" #include "base58.h" #include "hash.h"
int main() { uint8_t priv_bytes[32] = { 0x28,0x8f,0x39,0xbb,0xfd,0x36,0xda,0x5a, 0x12,0xd1,0x62,0xcb,0x18,0x97,0xc9,0x02, 0x28,0x8b,0x39,0xbb,0x36,0xda,0x5a,0x12, 0xd1,0x62,0xcb,0x18,0x97,0xc9,0x02,0x3d }; uint8_t wif_bytes[33]; char *wif;
const char wif_exp[] = "cNKkmrwHuShs2mvkVEKfXULxXhxRo3yy1cK6sq62uBp2Pc8Lsa76";
/* */
bbp_print_hex("priv", priv_bytes, sizeof(priv_bytes));
wif_bytes[0] = 0x80; memcpy(wif_bytes + 1, priv_bytes, 32);
wif = bbp_base58check(wif_bytes, 34); printf("WIF : %s\n", wif); printf("WIF (exp): %s\n", wif_exp); free(wif);

Your expected result is uncompressed. Uncompressed keys begin with a 5. Compressed begin with a K or L. Follow my instructions in the above post to get uncompressed keys. Also, note that most clients now use compressed keys as the public keys are smaller and thus save space.

Thanks Knight,
I got it, I had do a little trial and error to figure out what else I needed to change. Thank You!
Why can't we just have a script to do this so we don't have to compile each change?

Because c isn't a scripting language. If you want a script, find a program in a scripting language that does this.
