 # Linux uses the system's NSS library for its WebCrypto implementation, whereas
 # Windows, Mac and Android use a statically-linked BoringSSL.
 # As such:
 #
 #  (a) Support for RSA is not guaranteed as the system NSS may be ancient.
 #  (b) RSA-PSS, AES-CTR, ECDH, ECDSA, and HKDF have only been implemented for
 #      BoringSSL based WebCrypto.
 #
 # These issue will be resolved once Linux switches to BoringSSL
 # (http://crbug.com/338887).
