Historical Note RSA $129$
RSA $129$ is one of a number of large ($100$ digits and over) semiprimes offered up as a factorisation challenge by, and  as a demonstration of the effectiveness of their encryption algorithm now known as RSA.

In $1993$, a concerted effort was made by over $600$ academics and hobbyists, moderated over the Internet, to crack the code and so decipher the message which was hidden thereby.

It took less than a year to reveal the secret message:
