![]() Electronic fingerprints of all incoming and outgoing emails are created and stored in encrypted form. If there was an intrusion, the plaintext password is not lost. When users reenters their password, the new hash value is compared to the stored value. A plaintext password stored in the form of its associated hash value is more secure than a normal password. Comparing hash values ensures that downloaded documents are free from malicious code or transfer damage. When publishing documents on the internet or on an intranet, specifying hash values and using Secure Sockets Layer/ Transport Layer Security certificates increase document security. Cryptographic checksums can prevent the exploitation of images because the files cannot be modified for contrast characteristics or retouching. ![]() There are multiple post-processing phases that images undergo before they are published. While version control systems serve a similar function, checksums are considered more effective and secure. Cryptographic checksums help prevent unauthorized access and data manipulation. These algorithms also make it possible to acknowledge receipt of a file's last processing status.Ĭhecksums are used for applications such as the following: Cryptographic checksums form the foundation of cryptography today.Ĭryptographic checksums help authenticate files and their integrity. They are also known as message authentication codes, integrity check values, modification detection codes or message integrity codes. A cryptographic checksum is assigned to a file and is used to verify that the data in that file has not been tampered with or manipulated, possibly by a malicious entity.Ĭryptographic checksums provide the basis of modern cryptography, particularly for signing and encryption, digital signatures, email certificates and website certificates. This hash value is then used as a checksum to confirm that the sent file was not changed by an attacker.Ī hash value remains unchanged from the time it is created and is considered an "electronic fingerprint" of a file. ![]() The algorithm performs numerous mathematical operations to create a hash value, or fixed string of digits. Generated by a cryptographic algorithm, a cryptographic checksum is a mathematical value assigned to a file sent through a network for verifying that the data contained in that file is unchanged.
