Custom Random Number Generation Logic Verified
The custom random number generation logic for non-ESP32 platforms has been reviewed and found to be secure and efficient. The functions
rngStartandrngGenerateRandomNumberensure proper initialization and secure random number generation by leveraging hardware RNG capabilities with appropriate system locks and timeout handling.
rngStartinitializes the RNG peripheral and sets its state to ready.rngGenerateRandomNumberwaits for the RNG data register to be ready, retrieves a 32-bit random number, and handles timeouts appropriately.Scripts executed

CONFIG_MBEDTLS_X509_CSR_PARSE_Csetting disables support for parsing X.509 Certificate Signing Requests (CSRs), which reduces the code size but may limit the application's ability to handle certificate requests.
63-63: Enabling TLS 1.3 improves security and performance.The
CONFIG_MBEDTLS_SSL_PROTO_TLS1_3setting enables support for the TLS 1.3 protocol, which offers improved security and performance over previous versions. This is a recommended update.
64-64: Enabling session tickets improves session management and performance.The
CONFIG_MBEDTLS_CLIENT_SSL_SESSION_TICKETSsetting enables the use of session tickets for SSL client sessions, which improves session management and speeds up reconnections, enhancing overall performance.targets/ESP32/_IDF/sdkconfig.default_rev3_ipv6.esp32 (6)
54-54: Enabling peer certificate retention enhances security but may increase memory usage.The
CONFIG_MBEDTLS_SSL_KEEP_PEER_CERTIFICATEsetting enhances security by retaining the peer's certificate for verification purposes. However, be aware that this may increase memory usage.
55-55: Disabling the certificate bundle reduces code size but may affect functionality.The
CONFIG_MBEDTLS_CERTIFICATE_BUNDLEsetting disables the use of a certificate bundle, which reduces the code size but could affect applications relying on bundled certificates for SSL/TLS operations.
60-60: Disabling XTEA reduces cryptographic options but simplifies configuration.The
CONFIG_MBEDTLS_XTEA_Csetting disables the XTEA encryption algorithm, which may reduce the available cryptographic options but can simplify the configuration and reduce code size.
62-62: Disabling CSR parsing reduces code size but limits functionality.The
CONFIG_MBEDTLS_X509_CSR_PARSE_Csetting disables support for parsing X.509 Certificate Signing Requests (CSRs), which reduces the code size but may limit the application's ability to handle certificate requests.
63-63: Enabling TLS 1.3 improves security and performance.The
CONFIG_MBEDTLS_SSL_PROTO_TLS1_3setting enables support for the TLS 1.3 protocol, which offers improved security and performance over previous versions. This is a recommended update.
64-64: Enabling session tickets improves session management and performance.The
CONFIG_MBEDTLS_CLIENT_SSL_SESSION_TICKETSsetting enables the use of session tickets for SSL client sessions, which improves session management and speeds up reconnections, enhancing overall performance.targets/ESP32/_IDF/sdkconfig.default_pico (4)
71-71: Approved: Disabling XTEA cipher support.Disabling
CONFIG_MBEDTLS_XTEA_Cremoves support for the XTEA cipher, aligning with the objective to phase out older cryptographic methods.
73-73: Approved: Enabling X.509 CSR parsing.Enabling
CONFIG_MBEDTLS_X509_CSR_PARSE_Callows parsing of X.509 Certificate Signing Requests (CSRs), enhancing certificate management capabilities.
74-74: Approved: Enabling TLS 1.3 support.Enabling
CONFIG_MBEDTLS_SSL_PROTO_TLS1_3adds support for TLS 1.3, which provides enhanced security and performance.
75-75: Approved: Enabling SSL session tickets.Enabling
CONFIG_MBEDTLS_CLIENT_SSL_SESSION_TICKETSallows the use of SSL session tickets for improved session resumption, enhancing performance.targets/ESP32/_IDF/sdkconfig.default_ble_rev3.esp32 (5)
74-74: Approved: Retaining peer certificates.Enabling
CONFIG_MBEDTLS_SSL_KEEP_PEER_CERTIFICATEallows the system to retain peer certificates during SSL sessions, enhancing security context management.
79-79: Approved: Disabling XTEA cipher support.Disabling
CONFIG_MBEDTLS_XTEA_Cremoves support for the XTEA cipher, aligning with the objective to phase out older cryptographic methods.
81-81: Verify: Disabling X.509 CSR parsing.Disabling
CONFIG_MBEDTLS_X509_CSR_PARSE_Cmeans that parsing of X.509 Certificate Signing Requests (CSRs) is not enabled. Verify if this is intentional to limit features or reduce the footprint.
82-82: Approved: Enabling TLS 1.3 support.Enabling
CONFIG_MBEDTLS_SSL_PROTO_TLS1_3adds support for TLS 1.3, which provides enhanced security and performance.
83-83: Approved: Enabling SSL session tickets.Enabling
CONFIG_MBEDTLS_CLIENT_SSL_SESSION_TICKETSallows the use of SSL session tickets for improved session resumption, enhancing performance.
