       The SEED encryption algorithm for EVP.

       All modes below use a key length of 128 bits and acts on blocks of 128-bits.

       EVP_seed_cbc(), EVP_seed_cfb(), EVP_seed_cfb128(), EVP_seed_ecb(), EVP_seed_ofb()
           The SEED encryption algorithm in CBC, CFB, ECB and OFB modes respectively.

       Developers  should  be aware of the negative performance implications of calling these functions multiple
       times and should consider using EVP_CIPHER_fetch(3) with EVP_CIPHER-SEED(7) instead.   See  "Performance"
       in crypto(7) for further information.

       These  functions return an EVP_CIPHER structure that contains the implementation of the symmetric cipher.
       See EVP_CIPHER_meth_new(3) for details of the EVP_CIPHER structure.
