=head1 DESCRIPTION
PKCS5_PBKDF2_HMAC() derives a key from a password using a salt and iteration count
B<salt> is the salt used in the derivation of length B<saltlen>. If the
B<salt> is NULL, then B<saltlen> must be 0. The function will not
-attempt to calculate the length of the B<salt> because its not assumed to
+attempt to calculate the length of the B<salt> because it is not assumed to
be NULL terminated.
B<iter> is the iteration count and its value should be greater than or
equal to 1. RFC 2898 suggests an iteration count of at least 1000. Any
B<iter> less than 1 is treated as a single iteration.
-B<digest> is message digest function used in the derivation. Values include
+B<digest> is the message digest function used in the derivation. Values include
any of the EVP_* message digests. PKCS5_PBKDF2_HMAC_SHA1() calls
PKCS5_PBKDF2_HMAC() with EVP_sha1().
