* Simplify crypto IOV helpersGreg Hudson2013-05-244-189/+77
| | | | | | | | Expand the concept of an IOV block state into a cursor which remembers the IOV set being iterated over, the block size, and both input and output positions. Eliminate the no-copy inline block getter for now, but provide helpers to grab contiguous chains of blocks from a cursor. Also provide an inline helper to sum the total length of an iov chain.
* Reduce boilerplate in makefilesGreg Hudson2013-05-161-4/+0
| | | | | | | | | Provide default values in pre.in for PROG_LIBPATH, PROG_RPATH, SHLIB_DIRS, SHLIB_RDIRS, and STOBJLISTS so that they don't have to be specified in the common case. Rename KRB5_RUN_ENV and KRB5_RUN_VARS to RUN_SETUP (already the most commonly used name) and RUN_VARS. Make sure to use DEFINES for local defines (not DEFS). Remove some other unnecessary makefile content.
* Separate clpreauth and kdcpreauth interfacesGreg Hudson2012-12-191-6/+6
| | | | | | | Since there is no overlap between the clpreauth and kdcpreauth interface declarations, there's no particular reason to combine them into one header. For backward compatibility and convenience, leave behind a preauth_plugin.h which includes both.
* De-conditionalize Camellia codeGreg Hudson2012-10-091-22/+0
| | | | | | | | | | The Camellia enctypes and cksumtypes have received IANA assignments. Add #defines using those assignments to krb5.h, remove the CAMELLIA conditional, and enable testing code as appropriate. The Camellia draft has not received an RFC number yet, so there is no Doxygen markup for the enctype and cksumtype #defines. That can be added once the RFC number is known.

* Consolidate almost all lib/crypto/krb headers into a singleGreg Hudson2011-03-028-118/+61
| | | | | | | | | | | | | crypto_int.h. In that header, define and document responsibilities for crypto modules, some of which are satisfied through a module-specific crypto_mod.h. In the OpenSSL and NSS modules, remove many of the headers and sources providing functionality which isn't needed by lib/crypto/krb any more (direct interfaces to MD4, MD5, and SHA-1 hashing, as well as DES weak key testing). Change most Makefile.ins to only include headers from lib/crypto/krb and lib/crypto/$(CRYPTO_IMPL), instead of from many different directories. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24677 dc483132-0cff-0310-8789-dd5450dbe970
* Reference random-to-key handlers through the enctype instead of theGreg Hudson2011-02-276-35/+36
| | | | | | | | | | | | enc_provider, for consistency with string-to-key and the place of implementation (other enc_provider functions are implemented in the back end, but random-to-key handlers are in krb). Use a single handler for non-DES/DES3 enctypes since it's always just directly copying the bits. Collapse the three implementations (des, des3, and direct) into random_to_key.c, as they're very short, and eliminate the lib/crypto/krb/rand2key directory. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24669 dc483132-0cff-0310-8789-dd5450dbe970

* Fix cipher state chaining in OpenSSL back endGreg Hudson2010-02-183-61/+90
| | | | | | | | | | | | | | | | | | | | Make cipher state chaining work in the OpenSSL back end for des, des3, and arcfour enc providers. Subtleties: * DES and DES3 have checks to avoid clobbering ivec with uninitialized data if there is no data to encrypt. * Arcfour saves the OpenSSL cipher context across calls. To protect against a caller improperly copying the state (which happens to work with other enc providers), a loopback pointer is used, as in GSSAPI. * EVP_EncryptFinal_ex is unnecessary with stream ciphers and would interfere with cipher state chaining if it did anything, so just remove it. ticket: 6665 target_version: 1.8 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23734 dc483132-0cff-0310-8789-dd5450dbe970
* Restructure the crypto checksum implementation to minimizeGreg Hudson2009-12-104-1/+6
| | | | | | | | | | | | | | | | | | | | | dependencies on the internals of modules. * Keyhash providers are gone. * The cksumtypes table contains checksum and verify functions, similar to the etypes encrypt and decrypt functions. New checksum functions parallel the old keyhash providers, and there are also functions for unkeyed and derived-key HMAC checksums. * The flags field is now used to indicate whether a checksum is unkeyed, but not whether it is a derived-key HMAC checksum. * The descbc checksum is handled through a new enc_provider function which calculates a CBC MAC. The OpenSSL module does not implement the CBC MAC function (it didn't implement descbc before). builtin/des could probably get rid of f_cksum.c (the old DES CBC routine) with some alterations to string2key.c. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23462 dc483132-0cff-0310-8789-dd5450dbe970
* Consolidate the IOV and non-IOV encryption/decryption code paths, andGreg Hudson2009-12-045-757/+188
| | | | | | | | | | | | | | | | | | | | | | | | drop the _iov suffix from most encryption- and decryption-related functions. The enc_provider encrypt and decrypt functions take IOVs, as do the enctype entries in etypes.c, and there are no separate encrypt_iov or decrypt_iov functions. aead_provider is gone. Enctype functions now take pointers to the enctype entry instead of pointers to the enc/hash/aead providers; this allows dk_encrypt and dk_decrypt to be polymorphic in the length function they use now that AES and DES3 can't differentiate by aead provider. aes_string_to_key needed to be moved into the krb/ fold for this since it's an enctype function; it was duplicated between builtin/ and openssl/ before. This leaves openssl/aes empty; the build system currently demands that all modules have the same directory structure, so the directory and Makefile will stick around for now. Three separate copies of the derive_random logic are also now consolidated into one. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23444 dc483132-0cff-0310-8789-dd5450dbe970

* Move the arcfour directory from the crypto module dirs into krb. ThisGreg Hudson2009-11-272-26/+36
| | | | | | | | | | | | | directory contains the token encryption code (similar to dk, old, and raw) which is Kerberos-specific. The actual stream cipher lives in enc_provider/rc4.c, which is still in the module dirs. arcfour/arcfour-int.h contained the definitions of some structures used only in enc_provider/rc4.c. Move those definitions into that source file so that everything in arcfour is at the right level of abstraction to live in krb. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23367 dc483132-0cff-0310-8789-dd5450dbe970
