A PDF file may be encrypted, for security, in which case a password is needed to view or edit the contents. PDF 2.0 defines 256-bit AES encryption as the standard for PDF 2.0 files. The PDF Reference also defines ways that third parties can define their own encryption systems for PDF.
QOwnNotes is a free open source ( GPL) plain-text notepad. The program has support for markdown, and includes a to-do list manager that works on FreeBSD, Linux, MacOS and Windows. It can optionally work together with the notes application of ownCloud or Nextcloud .
Triple DES. In cryptography, Triple DES ( 3DES or TDES ), officially the Triple Data Encryption Algorithm ( TDEA or Triple DEA ), is a symmetric-key block cipher, which applies the DES cipher algorithm three times to each data block. The 56-bit key of the Data Encryption Standard (DES) is no longer considered adequate in the face of modern ...
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity). Implementation. HMAC - MD5. HMAC- SHA1.
VeraCrypt. VeraCrypt is a free and open-source utility for on-the-fly encryption (OTFE). [ 5] The software can create a virtual encrypted disk that works just like a regular disk but within a file. It can also encrypt a partition [ 6] or (in Windows) the entire storage device with pre-boot authentication.
The 140 series of Federal Information Processing Standards ( FIPS) are U.S. government computer security standards that specify requirements for cryptographic modules . As of October 2020, FIPS 140-2 and FIPS 140-3 are both accepted as current and active. [ 1] FIPS 140-3 was approved on March 22, 2019 as the successor to FIPS 140-2 and became ...
QPDF. QPDF is both a software library and a free command-line program that can convert one PDF file to another equivalent PDF file. It is capable of performing transformations such as linearization (also known as web optimization or fast web viewing), encryption, and decryption of PDF files. [ 2] It also has options for inspecting or checking ...
A High Assurance Internet Protocol Encryptor ( HAIPE) is a Type 1 encryption device that complies with the National Security Agency 's HAIPE IS (formerly the HAIPIS, the High Assurance Internet Protocol Interoperability Specification). The cryptography used is Suite A and Suite B, also specified by the NSA as part of the Cryptographic ...
