The EVP signature routines are a high level interface to digital signatures.
EVP_DigestSignInit() sets up signing context B<ctx> to use digest B<type> from
-ENGINE B<impl> and private key B<pkey>. B<ctx> must be created with
+ENGINE B<e> and private key B<pkey>. B<ctx> must be created with
EVP_MD_CTX_new() before calling this function. If B<pctx> is not NULL the
EVP_PKEY_CTX of the signing operation will be written to B<*pctx>: this can
be used to set alternative signing options.
written to B<siglen>.
EVP_DigestSign() signs B<tbslen> bytes of data at B<tbs> and places the
-signature in B<sig> and its length in B<siglen> in a simiilar way to
+signature in B<sig> and its length in B<siglen> in a similar way to
EVP_DigestSignFinal().
=head1 RETURN VALUES
EVP_DigestSignFinal() can be called later to digest and sign additional data.
Since only a copy of the digest context is ever finalized the context must
-be cleaned up after use by calling EVP_MD_CTX_cleanup() or a memory leak
+be cleaned up after use by calling EVP_MD_CTX_free() or a memory leak
will occur.
The use of EVP_PKEY_size() with these functions is discouraged because some
