define Package/libopenssl-afalg_sync/description
    This is an alternate AF_ALG engine for openssl, based on the devcrypto
    engine, but using the AF_ALG interface instead of /dev/crypto

    It is different than the AF_ALG engine that ships with OpenSSL:
     - it is faster
     - it uses sync calls, instead of async
     - it suports more algorithms
