143 (ECB) mode. It always transforms the input data, pointed to by
144 I<input>, into the output data, pointed to by the I<output> argument.

148 I<DES_set_key>. If I<encrypt> is zero (DES_DECRYPT), the I<input> (now
149 ciphertext) is decrypted into the I<output> (now cleartext). Input
152 DES_ecb3_encrypt() encrypts/decrypts the I<input> block by using
153 three-key Triple-DES encryption in ECB mode. This involves encrypting
154 the input with I<ks1>, decrypting with the key schedule I<ks2>, and
158 using ECB mode and I<ks1> as the key.
160 The macro DES_ecb2_encrypt() is provided to perform two-key Triple-DES
163 DES_ncbc_encrypt() encrypts/decrypts using the I<cipher-block-chaining>
164 (CBC) mode of DES. If the I<encrypt> argument is nonzero, the
165 routine cipher-block-chain encrypts the cleartext data pointed to by
166 the I<input> argument into the ciphertext pointed to by the I<output>
173 DES_xcbc_encrypt() is RSA's DESX mode of DES. It uses I<inw> and
179 three keys. This means that each DES operation inside the CBC mode is
180 C<C=E(ks3,D(ks2,E(ks1,M)))>. This mode is used by SSL.
182 The DES_ede2_cbc_encrypt() macro implements two-key Triple-DES by

226 DES_cbc_cksum() produces an 8 byte checksum based on the input stream
233 checksum from the input bytes. The algorithm can be iterated over the
234 input, depending on I<out_count>, 1, 2, 3 or 4 times. If I<output> is
235 non-NULL, the 8 bytes generated by each pass are written into

269 DES_cfb_encrypt() and DES_ofb_encrypt() operates on input of 8 bits.
271 first 12 bits will come from the 1st input byte and the low half of
272 the second input byte. The second 12 bits will have the low 8 bits
273 taken from the 3rd input byte and the top 4 bits taken from the 4th
274 input byte. The same holds for output. This function has been

303 DES_cbc_cksum() and DES_quad_cksum() return 4-byte integer representing the
304 last 4 bytes of the checksum of the input.
