Accidental (music) felt it was obvious that the accidental should continue. The older practice continued in use well into the 18th century by many composers, notably Johann Sebastian Bach.

In musical notation, the sharp (), flat (), and natural () symbols, among others, mark such notes—and those symbols are also called accidentals. In the measure
Lamport signature the "first" hash in the first pair, and so on. Then Bob hashes each of the 256 random numbers in Alice's signature. This gives him 256 hashes. If these 256 hashes exactly match the 256 hashes he just picked from Alice's public key then the signature is ok. If not, then the signature is wrong. Note that prior to Alice publishing the signature of the message, no one else knows the 2×256 random numbers in the private key. Thus, no one else can create the proper list of 256 random numbers for the signature. And after Alice has published the
