What is sodium software?
What is sodium software?
Sodium is a modern, easy-to-use software library for encryption, decryption, signatures, password hashing and more. It is a portable, cross-compilable, installable, packageable fork of NaCl, with a compatible API, and an extended API to improve usability even further. Sodium is cross-platforms and cross-languages.
What is libsodium Dev?
NaCl’s goal is to provide all of the core operations needed to build higher-level cryptographic tools. Sodium is a portable, cross-compilable, installable, packageable fork of NaCl, with a compatible API. This package provides development headers needed for applications that use libsodium.
What encryption does libsodium use?
PHP Encryption
Developers can use Sodium for PHP encryption and decryption with PHP 7.2 and newer without an extension. If you want to use Sodium with PHP 7.0 or 7.1, you need to install a PECL extension.
What is the use of libsodium?
Libsodium is used for reading and writing of encrypted files. systems, lighting, electric vehicles and others.

Chemical abbreviation for sodium chloride (table salt).
How do I install Libsodium devel?
Detailed Instructions:
- Run update command to update package repositories and get latest package information.
- Run the install command with -y flag to quickly install the packages and dependencies. sudo apt-get install -y libsodium-dev.
- Check the system logs to confirm that there are no related errors.
Is Libsodium FIPS compliant?
Update: Libsodium now has AES-256-GCM (as of 1.0. 4), which is one step closer to FIPS compliance. The bindings for libsodium do not yet exist in your language. Strong cryptography is illegal in your country.
Is Libsodium secure?
Overall our finding is that libsodium is indeed a secure, high-quality library that meets its stated usability and efficiency goals. We did not uncover any major vulnerabilities in the version of libsodium that we reviewed. During our review, we did identify several low severity issues in the libsodium 1.0.
What is r in cryptography?
R-Crypto is an easy-to-use disk encryption software that protects your confidential information and personal data on a desktop, notebook, or a removable data storage device against unauthorized access. To protect the data R-Crypto creates encrypted virtual disks (virtual data storage devices).
What is PHP extension sodium?
The php-sodium extension provides strong encryption capabilities in an easy and consistent way. Note that, for sites not having the extension installed, a php-openssl based solution, considered suboptimal, is used, and this fallback will stop working in a few versions (Moodle 4.2).
Why do we call it sodium?
The name derives from the English soda and Latin sodanum for “headache remedy”. The symbol Na derives from the Latin natrium for “natron” (soda in English). Sodium was discovered in 1807 by the English chemist Humphry Davy from electrolysis of caustic soda (NaOH).
How to decrypt an encrypted stream in Libsodium?
The crypto_secretstream_*_pull () functions set is the decryption counterpart. An encrypted stream starts with a short header, whose size is crypto_secretstream_xchacha20poly1305_HEADERBYTES bytes. That header must be sent/stored before the sequence of encrypted messages, as it is required to decrypt the stream.
How to generate a digital signature with sodium?
Digital signature: To generate a digital signature for a string, such as a message/file, Sodium uses an Elliptic Curve algorithm, Ed25519. Authenticated encryption with AES-GCM: Sodium offers authenticated encryption using the AES algorithm with Galois/Counter Mode (GCM).
Do you need an extension to use sodium in PHP?
Developers can use Sodium for PHP encryption and decryption with PHP 7.2 and newer without an extension. If you want to use Sodium with PHP 7.0 or 7.1, you need to install a PECL extension.
