digital envelope

Further it had three digital envelope generators, a noise generator, an LFO, and a chorus effect.

RSA standard that governs the application of cryptography to data, for example digital signatures and digital envelopes.

It featured Digitally controlled oscillators (DCOs) for tuning stability and digital envelope generation along with analog filters and signal path.

The oscillators are called "DCOs", and the envelope generated called a DEG (for Digital Envelope Generator).

Methods of Assurance Developers of the technology say the encryption will provide users with "digital envelopes" that cannot be opened except by the addressee, and the contents will have "digital signatures" that cannot be forged.

SAP does provide the SAP Cryptographic Library for free though, however this can only provide digital signatures and does not cover Digital Envelopes, Encryption, or Crypto Hardware (e.g., Smart Cards).
