These functions were added to glibc in version 2.1.īecause they employ the DES block cipher, which is no longerĬonsidered secure, ecb_crypt(), ecb_crypt(), crypt_r(), andĭes_setparity() were removed in glibc 2.28. If the value of flag is 0, the argument block is encrypted, other- wise it is decrypted.
