Giambattista della Porta's music cipher from De Furtivis Literarum Notis (1602). In cryptography, a music cipher is an algorithm for the encryption of a plaintext into musical symbols or sounds. Music-based ciphers are related to, but not the same as musical cryptograms.
There is a separate history of music ciphers utilizing music notation to encode messages for reasons of espionage or personal security that involved encryption and/or steganography. Because of the multitudinous ways in which notes and letters can be related, detecting hidden ciphers in music and proving accurate decipherment can be difficult.
Manuscript paper (sometimes staff paper in U.S. English, or just music paper) is paper preprinted with staves ready for musical notation. [1] A manuscript is made up of lines and spaces, and these lines and space have their names depending on the staves (bass or treble). Manuscript paper is also available for drum notation and guitar tabulature ...
This music manuscript was written by Johann Sebastian Bach and contains the Gavotte from his French Suite No. 5 (BWV 816). Music manuscripts are handwritten sources of music. Generally speaking, they can be written on paper or parchment. If the manuscript contains the composer's handwriting it is called an autograph.
The partially decomposed body of Ricky McCormick was discovered in a field in St. Charles County, Missouri on June 30, 1999. Sheriffs found two garbled hand-written notes – apparently written in secret code – in the victim's pockets, and these were handed over to the FBI for further investigation.
Encrypt/Decrypt data, using the AES cipher in various block modes (ECB, CBC, CFB, OFB and CTR, respectively). rCX contains the number of 16-byte blocks to encrypt/decrypt, rBX contains a pointer to an encryption key, ES:rAX a pointer to an initialization vector for block modes that need it, and ES:rDX a pointer to a control word.
AACS uses cryptography to control and restrict the use of digital media. It encrypts content under one or more title keys using the Advanced Encryption Standard (AES). Title keys are decrypted using a combination of a media key (encoded in a Media Key Block) and the Volume ID of the media (e.g., a physical serial number embedded on a pre-recorded disc).
Originally the Notenbuch was a bound volume comprising forty-eight pages of blank music paper, with eight staves on each page. Inscribed with the words Pour le clavecin (French: For the harpsichord), it was presented to Nannerl on the occasion of her eighth name day on 26 July 1759 (or possibly her eighth birthday, which fell on the 30th or 31st day of the same month).
