VanitySearch released
« on: March 22, 2020, 08:33:06 pm »


Groestlcoin VanitySearch: Vanity groestlcoin address generator . VanitySearch is a command-line vanity groestlcoin address generator. Add unique flair when you tell people to send groestlcoins.  Alternatively, VanitySearch can be used to generate random addresses offline.


If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

Features
• Fixed size arithmetic
• Fast Modular Inversion (Delayed Right Shift 62 bits)
• SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
• Use some properties of elliptic curve to generate more keys
• SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
• Multi-GPU support
• CUDA optimisation via inline PTX assembly
• Seed protected by pbkdf2_hmac_sha512 (BIP38)
• Support P2PKH, P2SH and BECH32 addresses
• Support split-key vanity address

Wildcards
Supported wildcard characters include: ? - any one character * - any number of characters

Considerations:
a pattern such as Ftest is the same as Ftest*
F?test will generate no matches, but F?test* will. If ? is used, then other wildcards must be used to match a 35 character address (for legacy addresses).
F?t* is the same asF?t???????????????????????????????

Impossible second character prefixes for F address
F1 F2 F3 F4 F5 F6 F7 F8 F9 Fw Fy Fu FU FP FA FS FD FF FG FH FJ FK FL Fz Fx FC Fv FV FB FN FM

Possible prefixes for 3 address
31h2 to 3R2c only
