| | | | | | | | | | | | | | | | | | | | | * d3_cbc.c (krb5int_des3_cbc_encrypt, krb5int_des3_cbc_decrypt): Don't declare left and right variables as registers. * f_cksum.c (mit_des_cbc_cksum): Likewise. * f_cbc.c (krb5int_des_cbc_encrypt, krb5int_des_cbc_decrypt): Likewise. (krb5int_des_cbc_encrypt): For full blocks, use GET_HALF_BLOCK to read and then xor, instead of processing each byte individually. (krb5int_des_do_encrypt_2, krb5int_des_do_decrypt_2) [CONFIG_SMALL]: New functions, wrapping large macros with the DES inner loops. * f_tables.h (DES_DO_ENCRYPT_1, DES_DO_DECRYPT_1): Renamed from non-_1 names. (krb5int_des_do_encrypt_2, krb5int_des_do_decrypt_2): Declare if CONFIG_SMALL is defined. (DES_DO_ENCRYPT, DES_DO_DECRYPT): Expand to _1 macros or _2 function calls depending on whether CONFIG_SMALL is defined. With CONFIG_SMALL defined, on x86/gcc/glibc, this drops about 5K (25%) of the code/table space. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@17183 dc483132-0cff-0310-8789-dd5450dbe970

Also include des_int.h. * destest.c: Change des_cblock to mit_des_cblock and add local prototypes. * cs_entry.c: Remove prototypes for mit_des_cbc_cksum and mit_des_cbc_cksum. Now in des_int.h. * cbc_cksum.c, string2key.c: Remove casts in call to mit_des_cbc_cksum * des_int.h: Add prototype for mit_des_cbc_verf_cksum. Change return code for mit_des_cbc_cksum to match source. * des.h: Remove unused structures and defines. Short end - fix des_int.h to reflect reality (i.e. source code) and then fix rest of code to agree. Also removed the use of old structures such as des_cblock and des_key_schedule. Instead the the newer mit_des_cblock and mit_des_schedule are used. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@6598 dc483132-0cff-0310-8789-dd5450dbe970
