140 evp \- high\-level cryptographic functions
148 The \s-1EVP\s0 library provides a high-level interface to cryptographic
149 functions.
151 The \fBEVP_Seal\fR\fI\s-1XXX\s0\fR and \fBEVP_Open\fR\fI\s-1XXX\s0\fR
152 functions provide public key encryption and decryption to implement digital \*(L"envelopes\*(R".
154 The \fBEVP_DigestSign\fR\fI\s-1XXX\s0\fR and
155 \&\fBEVP_DigestVerify\fR\fI\s-1XXX\s0\fR functions implement
157 \&\fBEVP_Sign\fR\fI\s-1XXX\s0\fR and \fBEVP_Verify\fR\fI\s-1XXX\s0\fR
158 functions.
160 Symmetric encryption is available with the \fBEVP_Encrypt\fR\fI\s-1XXX\s0\fR
161 functions.  The \fBEVP_Digest\fR\fI\s-1XXX\s0\fR functions provide message digests.
163 The \fB\s-1EVP_PKEY\s0\fR\fI\s-1XXX\s0\fR functions provide a high-level interface to
164 asymmetric algorithms. To create a new \s-1EVP_PKEY\s0 see
166 with a private key of a particular algorithm by using the functions
171 key back into an \s-1\fBOSSL_PARAM\s0\fR\|(3) array.
173 The \s-1EVP_PKEY\s0 functions support the full range of asymmetric algorithm operations:
177 …t these functions do not perform a digest of the data to be signed. Therefore, normally you would …
178 …e that these functions do not perform a digest of the data to be signed. Therefore, normally you w…

185 based encryption. Careful selection of the parameters will provide a PKCS#5 \s-1PBKDF1\s0 compatible
187 \&\s-1PBKDF2\s0 from PCKS#5).
189 The \fBEVP_Encode\fR\fI\s-1XXX\s0\fR and
190 \&\fBEVP_Decode\fR\fI\s-1XXX\s0\fR functions implement base 64 encoding
194 (public key algorithms) can be replaced by \s-1ENGINE\s0 modules providing alternative
195 implementations. If \s-1ENGINE\s0 implementations of ciphers or digests are registered
196 as defaults, then the various \s-1EVP\s0 functions will automatically use those
197 implementations automatically in preference to built in software
200 Although low-level algorithm specific functions exist for many algorithms
201 their use is discouraged. They cannot be used with an \s-1ENGINE\s0 and \s-1ENGINE\s0
202 versions of new algorithms cannot be accessed using the low-level functions.
204 cleanly supported at the low-level and some operations are more efficient
205 using the high-level interface.
