I will not be held liable for lost funds as a result of the use of this program. Also do not use this program for nefarious purposes! I do not condone illegal activity. The chances of actually brute forcing an address is nearly impossible anyways. Be sure to report any issues or bugs and fixes, I am happy to accept pull requests! If you have an altcoin you would like to add please let me know.
Running On Linux:. For generating addresses using the CPU slower use: vanitygen! For generating addresses using the GPU faster use: oclvanitygen! Address prefix must be at the end of the command. For Bitcoin it is BTC. Fix it by issuing the below commands, in turn either installing or downgrading libcrypto. The error comes from an incompatibility with the newer version of libcrypto. Most older projects have this same bug.

This value will be used to calculate the public key. Prepend this version number in front of the PrivateKeyHex value. The prefix version number is always 1 byte in size and the PrivateKeyHex is 32 bytes.
This Secure Hash Algorithm generates a bit byte signature which cannot be decrypted back to the original value it is a one-way cryptographic function. The HashA1 value is always 32 bytes or 64 characters long.

The HashA2 value is always 32 bytes or 64 characters long. Get the first 4 bytes or first 8 characters of the HashA2 value. These 4 bytes is the checksum value which will be used to validate the address. The ChecksumA value is always 4 bytes or 8 characters long. If your software does not support the compressed keys you can use the uncompressed public key PublicKeyUncompressed and uncompressed private key PrivateKeyWIFUncompressed.

Prepend this version number in front of the PrivateKeyHex value and also append the value 0x01 to indicate that it correspond to a compressed public key. The prefix version number and compression flag is always 1 byte in size and the PrivateKeyHex is 32 bytes. The HashB1 value is always 32 bytes or 64 characters long. The HashB2 value is always 32 bytes or 64 characters long. Get the first 4 bytes or first 8 characters of the HashB2 value.
The ChecksumB value is always 4 bytes or 8 characters long. A bit ECC public key should provide comparable security to a bit RSA public key thus less processing power is required.
Elliptic curves are called elliptic because of their relationship to elliptic integrals in mathematics. Elliptic curves have nothing to do with ellipses. Ellipses are formed by quadratic curves x 2. Elliptic curves are always cubic x 3. A finite field is a field with a finite number of elements, called its order the size of the underlying set. The number of elements is the prime number p.
F p is called the prime field of order p, and is the field of residue classes modulo p, where the p elements are denoted 0, The base point G is a predetermined point x G , y G on the elliptic curve that everyone uses to compute other points on the curve. The prime n which is the order of base point G. The parameter n determines which is the maximum value that can be turned into a Bitcoin private key. Any bit number in the range [1, n - 1] is a valid private key.
See Procedure to calculate x and y. The x value is always 32 bytes or 64 characters long. The y value is always 32 bytes or 64 characters long. The PublicKey is the concatenation of the calculated x and y value. The PublicKey is always 64 bytes or characters long. Calculate PublicKey Uncompressed. There are two types of PublickKeys, the compressed and uncompressed. Prepend prefix value "04" in front of the PublickKey value to indicate that the PublickKey is uncompressed.
The prefix value is always 1 byte in size and the PublickKey is 64 bytes. Compressed keys only specify the x coordinate plus an 1 byte flag indicating which side of the symmetrical curve the point is on, which allows y to be derived. Uncompressed keys is represented by two coordinates x , y and there is a 1 byte prefix added. Bitcoin originally only used uncompressed public keys, but since v0. It is recommended to use the compressed public keys PublicKeyVersionComp because they are smaller, resulting in smaller transactions on the network, saving block chain size for everyone.
The HashC1 value is always 32 bytes or 64 characters long.
