profanity2

Update: use 1inch's profanity2 instead. It doens't generate private keys at all.

This is a fork of Profanity that uses safe 64-bit seed values.

	std::random_device rd;
	std::uint64_t value = rd();
	value = (value << 32) | rd();
	std::mt19937_64 eng(value);

Profanity is a high performance (probably the fastest!) vanity address generator for Ethereum. Create cool customized addresses that you never realized you needed! Recieve Ether in style! Wow!

Always verify that a private key generated by this program corresponds to the public key printed by importing it to a wallet of your choice. This program like any software might contain bugs and it does by design cut corners to improve overall performance.

Usage

usage: ./profanity [OPTIONS]

  Basic modes:
    --benchmark             Run without any scoring, a benchmark.
    --zeros                 Score on zeros anywhere in hash.
    --letters               Score on letters anywhere in hash.
    --numbers               Score on numbers anywhere in hash.
    --mirror                Score on mirroring from center.
    --leading-doubles       Score on hashes leading with hexadecimal pairs

  Modes with arguments:
    --leading <single hex>  Score on hashes leading with given hex character.
    --matching <hex string> Score on hashes matching given hex string.

  Advanced modes:
    --contract              Instead of account address, score the contract
                            address created by the account's zeroth transaction.
    --leading-range         Scores on hashes leading with characters within
                            given range.
    --range                 Scores on hashes having characters within given
                            range anywhere.

  Range:
    -m, --min <0-15>        Set range minimum (inclusive), 0 is '0' 15 is 'f'.
    -M, --max <0-15>        Set range maximum (inclusive), 0 is '0' 15 is 'f'.

  Device control:
    -s, --skip <index>      Skip device given by index.
    -n, --no-cache          Don't load cached pre-compiled version of kernel.

  Tweaking:
    -w, --work <size>       Set OpenCL local work size. [default = 64]
    -W, --work-max <size>   Set OpenCL maximum work size. [default = -i * -I]
    -i, --inverse-size      Set size of modular inverses to calculate in one
                            work item. [default = 255]
    -I, --inverse-multiple  Set how many above work items will run in
                            parallell. [default = 16384]

  Examples:
    ./profanity --leading f
    ./profanity --matching dead
    ./profanity --matching badXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXbad
    ./profanity --leading-range -m 0 -M 1
    ./profanity --leading-range -m 10 -M 12
    ./profanity --range -m 0 -M 1
    ./profanity --contract --leading 0
