+EVP_PKEY_CTX_set_paillier_keygen_bits,
+EVP_PKEY_CTX_get_paillier_keygen_bits - Paillier EVP_PKEY ctrls
+
+=head1 SYNOPSIS
+
+ #include <openssl/paillier.h>
+
+ int EVP_PKEY_CTX_set_paillier_keygen_bits(EVP_PKEY_CTX *ctx, int nbits);
+ int EVP_PKEY_CTX_get_paillier_keygen_bits(EVP_PKEY_CTX *ctx);
+
+=head1 DESCRIPTION
+
+Applications should use the higher level functions
+L<EVP_DigestInit(3)> etc. instead of calling the hash
+functions directly.
+
+SM3 (ShangMi#3 Hash Algorithm) is a cryptographic hash function with a
+256 bit output.
+
+sm3() computes the SM3 message digest of the B<n>
+bytes at B<d> and places it in B<md> (which must have space for
+SHA_DIGEST_LENGTH == 20 bytes of output). If B<md> is NULL, the digest
+is placed in a static array. Note: setting B<md> to NULL is B<not thread safe>.
+
+The following functions may be used if the message is not completely
+stored in memory:
+
+sm3_nit() initializes a B<sm3_ctx_t> structure.
+
+sm3_update() can be called repeatedly with chunks of the message to
+be hashed (B<len> bytes at B<data>).
+
+sm3_final() places the message digest in B<md>, which must have space
+for SM3_DIGEST_LENGTH == 32 bytes of output, and erases the B<sm3_ctx_t>.
+
+=head1 RETURN VALUES
+
+sm3_init(), sm3_update(), sm3_final(), sm3_compress() and sm3() return void.
