The tables below compare cryptographylibraries that deal with cryptography algorithms and have application programming interface (API) function calls to each of the supported features.

FIPS 140
This table denotes, if a cryptography library provides the technical requisites for FIPS 140, and the status of their FIPS 140 certification (according to NIST's CMVP search,[27] modules in process list[28] and implementation under test list).[29]
^Crypto++ received three FIPS 140 validations from 2003 through 2008. In 2016 NIST moved Crypto++ to the Historical Validation List.
^While GnuTLS is not FIPS 140-2 validated by GnuTLS.org, validations exist for versions from Amazon Web Services Inc., Oracle Corporation, Red Hat Inc. and SUSE LLC.
^While none of default JDK JCA/JCE providers is FIPS 140-2 validated, there are other JCE/JCA third party providers which are FIPS 140-2 validated.
^While Libgcrypt is not FIPS 140-2 validated by g10code, validations exist for versions from Amazon Web Services Inc., Canonical Ltd., Oracle Corporation, Red Hat Inc. and SUSE LLC.
^While the Network Security Services (NSS) are not FIPS 140-2 validated by the Mozilla Foundation, validations exist for versions from Amazon Web Services Inc., Canonical Ltd., Cisco Systems Inc., Hewlett Packard Enterprise, Oracle Corporation, Red Hat Inc., SafeLogic Inc., SUSE LLC and Trend Micro Inc.
^While OpenSSL is not FIPS 140-2 validated by OpenSSL.org, validations exist for versions from Amazon Web Services Inc., Aqua Security Software Ltd., Broadcom Inc., Canonical Ltd., Cisco Systems Inc., Cohesity Inc., ControlUp Technologies Inc., Crestron Electronics Inc., Dell Inc., Gallagher Group, Hewlett Packard Enterprise, IBM Corporation, ICU Medical Inc., Intelligent Waves, Ixia, KeyPair Consulting Inc., Koninklijke Philips N.V., Lenovo Group Limited, LG Electronics Inc., LogRhythm, McAfee LLC, Metaswitch Networks Ltd, NetBrain Technologies Inc., Nutanix Inc., Onclave Networks Inc., Oracle Corporation, REDCOM Laboratories Inc., Red Hat Inc., SafeLogic Inc., Super Micro Computer Inc., SUSE LLC, Tanium Inc., Trend Micro Inc., Unisys Corporation, Verizon, VMware Inc. and Wickr Inc.
Key operations
Key operations include key generation algorithms, key exchange agreements, and public key cryptography standards.
^The library offers X.509 and PKCS #8 encoding without PEM by default. For PEM encoding of public and private keys the PEM Pack is needed.
^ abcdeThese Public Key Cryptographic Standards (PKCS) are supported by accompanying libraries and tools, which are also part of the GnuPG framework, although not by the actual libgcrypt library.
Hash functions
Comparison of supported cryptographic hash functions. 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.
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).
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 can be broken up into the possible key sizes and block cipher modes it can be run with.
The table below shows the support of 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.
These tables compare the ability to use hardware enhanced cryptography. By using the assistance of specific hardware, the library can achieve greater speeds and/or improved security than otherwise.
^ abAltiVec includes POWER4 through POWER8 SIMD processing. POWER8 added in-core crypto, which provides accelerated AES, SHA and PMUL similar to ARMv8.1.
^ abcdeWhen using RSA BSAFE Crypto-J in native mode using BSAFE Crypto-C Micro Edition
^Crypto++ only provides access to the Padlock random number generator. Other functions, like AES acceleration, are not provided.
Windows 10/11, Windows Server 2019/2022, Red Hat Enterprise Linux (RHEL) 8/9, SUSE Linux Enterprise Server (SLES) 15 SP4 / SP5 / SP6, Ubuntu 22.04 LTS / 24.04 LTS, Rocky Linux 9, Fedora 39 / 40, Debian 12
^Crypto++ is thread safe at the object level, i.e. there is no shared data among instances. If two different threads access the same object then the user is responsible for locking.
