Hello Community , im new here and want to factor a prime factor of 512 bit i can input here this key so that all can access to it ? |

NFS@Home pretty much only accepts numbers that have some sort of mathematical interest. I don't speak for Greg, but it's unlikely you'll convince anyone to break an RSA key for you. |

Only RSA-1024, RSA-2048 and RSA-4096 has yet to be factorized. |

If you mean the numbers from the old RSA contest, actually there are many numbers up to 2048 bits that have not been factored. It's true there hasn't been an RSA-type key larger than RSA768 (publicly) factored since 2010. |

Please have me excused, but I had to look up "512-bit number". Apparently there is a fact that there is no single RSA-512, RSA-768, RSA-1024, RSA-2048 or RSA-4096 number. For each RSA designation, there happens to be several such numbers, probably less of them the higher you go. This number is an example of a RSA-155 and is consisting of 155 decimal digits: 109417386415705274218097073220403576120037329454492059909138421314763499842889 34784717997257891267332497625752899781833797076537244027146743531593354333897 Its factors are 102639592829741105772054196573991675900716567808038066803341933521790711307779 and 106603488380168454820927220360012878679207958575989291522270608237193062808643 http://en.wikipedia.org/wiki/RSA_numbers#RSA-155 So why not try factoring 77904004346346670503878542786396000104129136321344930547891284768371445950925377 67310826689425715004160093034133595468941695387445233512928852161531387989 instead. It is a RSA-512 number and apparently has not been factored yet. |

Should I perhaps make a check on the PRP1073 that is around here? |

Where is the dancing lady (or woman) located / or to be found? |

512 bits is not large enough to require NFS@Home; a single machine can do the job in a few core-weeks. |
