This package provides a thin Python wrapper around tzdata.

Utility that fakes the system time by pre-loading a small library that modifies the time, gettimeofday and clock_gettime system calls.

This small Python module parses various kinds of time expressions.

tz helps you schedule things across time zones. It is an interactive TUI program that displays time across a few time zones of your choosing.

This package contains a library for parsing ISO 8601 datetime strings.

The strict_rfc3339 Python module provides strict, simple, lightweight RFC3339 (Date and Time on the Internet: Timestamps) procedures.

It enables or aims to:

• Convert UNIX timestamps to and from RFC3339.

• Produce RFC3339 strings with a UTC offset (Z) or with the offset that the C time module reports is the local timezone offset.

• Be simple with minimal dependencies/libraries.

• Avoid timezones as much as possible.

• Be very strict and follow RFC3339.

This module provides a monotonic() function which returns the value (in fractional seconds) of a clock which never goes backwards.

GNU libtasn1 is a library implementing the ASN.1 notation. It is used for transmitting machine-neutral encodings of data objects in computer networking, allowing for formal validation of data according to some specifications.

This package provides Guile bindings to GnuTLS, a library implementation the TLS protocol. It supersedes the Guile bindings that were formerly provided as part of GnuTLS.

AWS libcrypto (aws-lc) contains portable C implementations of algorithms needed for TLS and common applications, and includes optimized assembly versions for x86 and ARM.

OpenSSL is an implementation of SSL/TLS.

p11-kit provides a way to load and enumerate PKCS#11 modules. It provides a standard configuration setup for installing PKCS#11 modules in such a way that they are discoverable. It also solves problems with coordinating the use of PKCS#11 by different components or libraries living in the same process.

mbed TLS, formerly known as PolarSSL, makes it trivially easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) products, facilitating this functionality with a minimal coding footprint.

Crypt::OpenSSL::RSA does RSA encoding and decoding (using the OpenSSL libraries).

mbed TLS, formerly known as PolarSSL, makes it trivially easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) products, facilitating this functionality with a minimal coding footprint.

The Crypt::OpenSSL::Guess Perl module provides helpers to guess the correct OpenSSL include path. It is intended for use in your Makefile.PL.

Dehydrated is a client for obtaining certificates from an ACME server (such as Let's Encrypt) implemented as a relatively simple Bash script.

Crypt::OpenSSL::Bignum provides multiprecision integer arithmetic in Perl.

GnuTLS is a secure communications library implementing the SSL, TLS and DTLS protocols. It is provided in the form of a C library to support the protocols, as well as to parse and write X.509, PKCS #12, OpenPGP and other required structures.

BearSSL is an implementation of the SSL/TLS protocol (RFC 5246) written in C. It aims at being correct and secure. In particular, insecure protocol versions and choices of algorithms are not supported, by design; cryptographic algorithm implementations are constant-time by default. It should also be small, both in RAM and code footprint. For instance, a minimal server implementation may fit in about 20 kilobytes of compiled code and 25 kilobytes of RAM.

mbed TLS, formerly known as PolarSSL, makes it trivially easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) products, facilitating this functionality with a minimal coding footprint.

This library provides a C99 implementation of SSL/TLS. It is designed to be familiar to users of the widely-used POSIX I/O APIs. It supports blocking, non-blocking, and full-duplex I/O. There are no locks or mutexes.

As it can be difficult to keep track of which encryption algorithms and protocols are best to use, s2n-tls features a simple API to use the latest default set of preferences. Remaining on a specific version for backwards compatibility is also supported.

Crypt::OpenSSL::Random is a OpenSSL/LibreSSL pseudo-random number generator
