Cryptography can be used to ensure data integrity as well as maintain secrecy. Using cryptography, it becomes possible to verify the origin of data and messages. This is done using digital signatures. When using cryptographic methods, the only part that must remain secret is the cryptographic keys. The algorithms, the key sizes, and file formats can be made public without compromising security.
Cryptography allows a series of operations or actions on data.
Signature is similar to physically signing a document, and initialing each section to show that no portion of the document has changed. Certificates are signed documents which match public keys to other information. All rights reserved. Terms of use .
