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)
