Definition
RSA $130$ is the name given to the semiprime:
- $1 \, 807 \, 082 \, 088 \, 687 \, 404 \, 805 \, 951 \, 656 \, 164 \, 405 \, 905 \, 566 \, 278 \, 102 \, 516 \, 769 \, 401 \, 349 \, 170 \, 127 \, 021 \, 450 \, 056 \, 662 \, 540 \, 244 \, 048 \, 387 \, 341 \, 127 \, 590 \, 812 \, 303 \, 371 \, 781 \, 887 \, 966 \, 563 \, 182 \, 013 \, 214 \, 880 \, 557$
Its factors are:
- $39 \, 685 \, 999 \, 459 \, 597 \, 454 \, 290 \, 161 \, 126 \, 162 \, 883 \, 786 \, 067 \, 576 \, 449 \, 112 \, 810 \, 064 \, 832 \, 555 \, 157 \, 243$
and:
- $45 \, 534 \, 498 \, 646 \, 735 \, 972 \, 188 \, 403 \, 686 \, 897 \, 274 \, 408 \, 864 \, 356 \, 301 \, 263 \, 205 \, 069 \, 600 \, 999 \, 044 \, 599$
Historical Note
RSA $130$ is one of a number of large ($100$ digits and over) semiprimes offered up as a factorisation challenge by Ronald Linn Rivest, Adi Shamir and Leonard Max Adleman as a demonstration of the effectiveness of their encryption algorithm now known as RSA.
On $12$th April $1996$, RSA $130$ was successfully factorised into its $2$ prime factors by a Dutch team.
