The tables below compare cryptography libraries that deal with cryptography algorithms and have api function calls to each of the supported features.
Contents
Key operations
Key operations include key generation algorithms, key exchange agreements and public key cryptography standards.
Hash functions
Comparison of supported cryptographic hash functions. At the moment this section also includes ciphers that are used for producing a MAC tag for a message. Here hash functions are defined as taking an arbitrary length message and producing a fixed size output that is virtually impossible to use for recreating the original message.
MAC algorithms
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).
Block ciphers
Table compares implementations of block ciphers. Block ciphers are defined as being deterministic and operating on a set number of bits (termed a block) using a symmetric key. Each block cipher where applicable is broken up into the possible key size and what mode it can be run with, i.e. CBC, CTR.
Stream ciphers
Table compares implementations of the various stream ciphers. Stream ciphers are defined as using plain text digits that are combined with a pseudorandom cipher digit stream. Stream ciphers are typically faster than block ciphers and may have lower hardware complexity, but may be more susceptible to attacks.
Hardware-assisted support
Table compares the ability to utilize hardware enhanced cryptography. With using the assistance of specific hardware the library can achieve faster speeds than otherwise. This is done through hardware that has been designed in such a way as to handle cryptography better.
