The listing of these third party products does not imply any endorsement by the OpenSSL project, and these organizations are not affiliated in any way with OpenSSL other than by the reference to their independent web sites here. This service is primarily for operating systems where there are no pre-compiled OpenSSL packages. If you are such a user, we ask you to get in touch with your distributor first.
Those are already well-known among the users of said distributions, and will therefore not be mentioned here. Note: many Linux distributions come with pre-compiled OpenSSL packages. The condition to get a link here is that the link is stable and can provide continued support for OpenSSL for a while. The pack/ unpack methods can be used to convert between binary bytes and decimal form of the numbers (both of type string, but one is binary and one is ASCII), but they will always try to cast the ASCII string into a 32-bit int on 32-bit systems.Some people have offered to provide OpenSSL binary distributions for selected operating systems. This has several advantages, such as the convenience in presenting to the user, and the ability to manipulate it with bcmath directly. There are several ways to do so, such as creating an array with two numbers, or converting the integer into its decimal human-readable form. However, since 64-bit systems and many other languages support storing signed long long integers, it is sometimes necessary to store this range of integers in exact value. On 32-bit systems, integers greater than 0x7FFFFFFF cannot be stored primitively, while integers between 0x0000000080000000 and 0x7FFFFFFFFFFFFFFF can be stored primitively on 64-bit systems but not 32-bit systems ( signed long long).
