166 This library contains a fast implementation of the DES encryption
169 There are two phases to the use of DES encryption.  The first is the
171 actual encryption.  A DES key is of type \fIDES_cblock\fR. This type
182 Before a DES key can be used, it must be converted into the
202 \&\fBDES_ecb_encrypt()\fR is the basic DES encryption routine that encrypts or
214 three-key Triple-DES encryption in ECB mode.  This involves encrypting
217 of brute force breaking of DES and has the advantage of if \fIks1\fR,
221 The macro \fBDES_ecb2_encrypt()\fR is provided to perform two-key Triple-DES
225 (CBC) mode of DES.  If the \fIencrypt\fR argument is nonzero, the
234 \&\fBDES_xcbc_encrypt()\fR is RSA's DESX mode of DES.  It uses \fIinw\fR and
237 of 24 bytes.  This is much better than CBC DES.
239 \&\fBDES_ede3_cbc_encrypt()\fR implements outer triple CBC DES encryption with
240 three keys. This means that each DES operation inside the CBC mode is
243 The \fBDES_ede2_cbc_encrypt()\fR macro implements two-key Triple-DES by
245 This form of Triple-DES is used by the RSAREF library.

344 The \fBdes\fR library was written to be source code compatible with
351 Single-key DES is insecure due to its short key size.  ECB mode is
