In the latest release of wolfSSL, we have added a new port for using wolfSSL with OpenVSwitch. OpenVSwitch is a multilayer switch to provide switching for hardware virtualization environments. With wolfSSL support, users can now build OpenVSwitch with the configure option --with-wolfssl. 

The addition of OpenVSwitch is available in wolfSSL 4.2.0, which can be downloaded here. 

Changes made to OpenVSwitch for wolfSSL compatibility can be found on the OpenVSwitch GitHub. 

For more information about the compatibility layer, building with OpenVSwitch, or any additional questions, contact us at facts@wolfssl.com.

We have added in support for the open source project WebRTC (https://webrtc.org/) in wolfSSL release 4.2.0. This is a project that allows real time communication (RTC) with IoT, mobile and web browsers. Many additional API where added to the wolfSSL compatibility layer in order to plug wolfSSL into WebRTC instead of OpenSSL. Some of those additional API added are:

• SSL_CIPHER_get_id
• SSL_CIPHER_get_rfc_name
• SSL_get_cipher_by_value
• X509_print_ex
• X509_NAME_add_entry_by_NID
• X509_time_adj
• X509_time_adj_ex
• DTLSv1_get_timeout
• DTLSv1_handle_timeout
• DTLSv1_set_initial_timeout_duration
• SSL_CTX_set_current_time_cb
• PEM_write_bio_RSA_PUBKEY
• PEM_read_bio_RSA_PUBKEY
• PEM_write_bio_PUBKEY
• EVP_PKEY_missing_parameters
• EVP_PKEY_cmp
• BN_is_negative
• BIO_set_retry_write

For questions about the use of wolfSSL with WebRTC contact us at facts@wolfssl.com.

The option to have a massive TITAN size session cache is now available in wolfSSL 4.2.0. This can hold over 2 million session entries and works well for use in desktops and high load environments that have many long lasting session ID’s. To turn on the new session cache size use the enable option --enable-titancache, or the macro TITAN_SESSION_CACHE if building without autoconf. This option is meant for extreme use cases where --enable-hugecache (HUGE_SESSION_CACHE) is just not enough. It works well with systems that need over 200 new sessions per second and also need to handle numerous long lasting sessions.

For more information about the TITAN cache build contact us at facts@wolfssl.com.

Are you a MQX user looking for SFTP client or server support?  If so, you’ll be happy to hear that wolfSSH SFTP now supports NXP/Freescale MQX 4.2!

MQX 4.2 support (using the MFS file system and RTCS TCP/IP stack) was added as part of the wolfSSH 1.4.3 release.  MQX 4.2, or “MQX Classic”, is a Real-Time Operating System (RTOS) created by NXP/Freescale and commonly used on 32-bit MCUs and MPUs from NXP.  The wolfSSH SFTP MQX 4.2 port was tested and validated on a NXP K70-based platform.  When compiling wolfSSH for NXP/Freescale MQX 4.2, the FREESCALE_MQX define should be used.

wolfSSH is a lightweight, portable SSHv2 implementation with support for both client and server functionalities.  Including features such as SFTP and SCP, and supporting both password and public key authentication, wolfSSH is the ideal solution for SSH and file transfer requirements on embedded systems.  wolfSSH is backed by the wolfCrypt cryptography library and can use features of wolfCrypt such as expansive hardware cryptography support, FIPS 140-2 validated cryptography, DO-178, and more!

wolfSSH can be downloaded from the wolfSSL download page or via GitHub.  Please contact facts@wolfssl.com with any questions or inquiries.

wolfSSL has added in many new OpenSSL compatibility API’s in the recent release, wolfSSL 4.2.0. The compatibility layer previously was impressive with upwards of 600 hundred of the most common API used, but in the effort to make transitioning projects that currently use OpenSSL, over to using wolfSSL, we added more than 198 additional API. These API additions supported many open source projects such as building with Apache (https://www.apache.org/) and WebRTC. There were also improvements done in the last release for existing API’s and enhancements to their functionality.

There are too many new API to list all, but here are some of them:

• SSL_CIPHER_get_id
• SSL_CIPHER_get_rfc_name
• SSL_get_cipher_by_value
• X509_print_ex
• X509_NAME_add_entry_by_NID
• X509_time_adj
• X509_time_adj_ex
• DTLSv1_get_timeout
• DTLSv1_handle_timeout
• DTLSv1_set_initial_timeout_duration
• SSL_CTX_set_current_time_cb
• PEM_write_bio_RSA_PUBKEY
• PEM_read_bio_RSA_PUBKEY
• PEM_write_bio_PUBKEY
• EVP_PKEY_missing_parameters
• EVP_PKEY_cmp
• BN_is_negative
• BIO_set_retry_write
• ASN1_STRING_type
• EVP_aes_128_gcm, EVP_aes_192_gcm, EVP_aes_256_gcm
• EVP_CIPHER_CTX_ctrl
• EVP_PKEY_sign
• EVP_PKEY_sign_init
• RSA_print
• RSA_NO_PADDING
• RSA_PKCS1_PSS_PADDING
• wolfSSL_EVP_CIPHER_CTX_set_iv_length
• GENERAL_NAMES_free
• i2a_ASN1_OBJECT
• PKCS5_PBKDF2_HMAC
• X509_get_ext_by_NID
• X509V3_EXT_print
• ASN1_STRING_print
• GENERAL_NAME_free
• …. (and more)

If you have a FIPS project in jeopardy with the upcoming lapse in OpenSSL support, an easy fix is to plug in wolfSSL. Let us know if your project needs any API that we are missing by contacting us at facts@wolfssl.com.

wolfSSH v1.4.3 has been released. This version of wolfSSH includes several fixes and new features. The primary new feature is a wolfSFTP port to MQX 4.2. Please see the change log for more details. Included are some portability fixes between versions of C compilers, a clean up of some obvious issues with the examples, and improved interoperability with PuTTY.

You can download this latest release from the wolfSSL download portal. Additional information wolfSSH can be found on the wolfSSH product page. For more information on platform support or for questions regarding wolfSSH, contact us at facts@wolfssl.com. Be sure to stay up to date with our GitHub repository. Please give us a star!
