2009-07-05Buffer in RMD160_CTX is length RMD160_BLOCK_LENGTH not RMD160_DIGEST_LENGTH.Todd C. Miller
Userland version was already correct. From Jason Fritcher. OK deraadt@
2009-02-17variable no longer usedTheo de Raadt
2009-02-17The loop here preparing the uio always added the length of the firstOwain Ainsworth
iovec, not the correct one. It worked ok since iovcnt was always 1. Since it's unlikely to be any other number, remove the loop and just add the one length we care about. "go ahead" deraadt@.
2008-11-04Use defines for constants. Use __attribute__ bounded.Hans-Joerg Hoexer

2008-10-30reintroduce mutexes to workqs for locking.David Gwynne

2008-08-12Implementation of the HMAC-MD5, HMAC-SHA1, HMAC-SHA256, AES-128-CMACDamien Bergamini
and AES Key Wrap algorithms. They will replace/extend the non-generic implementation in net80211. AES-128-CMAC tested by sobrado@ (AlphaServer 1200), naddy@ (alpha/sparc64) and sthen@ (sparc64, armish). HMAC-* reviewed by hshoexer@ ok and hints from djm@
2008-07-21gives this a chance to work on architectures with strict alignmentDamien Bergamini
constraints.
2008-06-25implement automatic time-based rekeying (every 10 minutes); ok deraadt@Damien Miller
2008-06-09Introduce a facility to generate unpredictable 32 bit numbers withDamien Miller
near maximal (2^32) cycle times. These are useful for network IDs in cases where there are negative consequences to ID prediction and/or reuse. Use the idgen32() functions to generate IPv6 IDs and NFS client/server XIDs. Pseudorandom permutation code in crypto/idgen.c based on public domain skip32.c from Greg Rose. feedback & ok thib@ deraadt@

2008-06-09Implement the AES XTS mode of operation for the crypto(9) framework.Damien Miller
XTS is a "tweaked" AES mode that has properties that are desirable for block device encryption and it is specified in the IEEE P1619-2007 standard for this purpose. prodded by & ok hshoexer@
2008-06-09constify arguments in wrapper functions; the lower level functionsDamien Miller
were already done

2007-11-28finish conversion to workq. remove list remnants, and put spl in the rightTed Unangst
places. handle the no workq case here. ok deraadt

2007-11-25convert crypto thread to workq. add WQ_DIRECTOK flag to workq.Ted Unangst
combined, this lets us use crypto before the thread is running and therefore cryptoraid can attach nice and early. ok/testing deraadt mbalmer marco
2007-11-14do not call crypto_done() on errors, since the drivers already do this.Markus Friedl
otherwise we call the callback twice; fixes panics on crypto errors as seen on reboot; ok hshoexer

2007-09-11Add __bounded__ attributes to prototypes.Damien Miller
Use (x & 0xff) rather than (x % 256) - compilers generate faster code. Add arc4_getbytes function to extract raw keystream ok markus@ tom@
2007-09-10Make the hmac ipad/opad globals "const" and fixup the crypto functionsHenric Jungheim
to match. ok deraadt@
2007-07-24add rc4_skip() function that can be used to discard bytes fromDamien Bergamini
the arc4 key stream. rc4_skip(ctx, len); is equivalent to: u_int8_t dummy[len]; rc4_crypt(ctx, dummy, dummy, len); except that is does not require storage space and that it saves some cpu cycles. ok deraadt@
2007-07-20unbreak landisk kernel sha1 by working around a compiler bug;Otto Moerbeek
also brings kernel sha1 more in line with userland; discussed with miod@ and millert@;

2007-02-21Don't use arbitrary 128 bytes as size of the blf key array if we know exactlyAlexander von Gernler
how much blowfish takes at max, which is 72 bytes. Also define a constant for this in the include file, suggested by ray@. ok pedro@ thib@ tedu@
2007-02-19minimum blocksize for ESP is 32 bit, so adjust blocksize of NULLHans-Joerg Hoexer
encryption accordingly. Makes NULL encryption useable with ESP. Noticed by Martin Hedenfalk <martin.hedenfalk at gmail.com>. ok markus@

put one splx in a better spot. make a variable size MALLOC use malloc. remove null test after malloc(M_WAITOK). add PR_NOWAIT flag to pool_get instead of 0. change callbacks to correct type. ok brad deraadt markus mickey

2004-06-20In crypto_thread(), always save return value from splimp(). We were onlyAaron Campbell
storing it once on kernel startup. Scary. "holy crap" --deraadt. art@ ok Unclear if this was actually a problem in practice, but this doesn't hurt.
2004-05-07Replace RSA-derived md5 code with code derived from Colin Plumb's PD version.Todd C. Miller
This moves md5.c out of libkern and into sys/crypto where it belongs (as requested by markus@). Note that md5.c is still mandatory (dev/rnd.c uses it). Verified with IPsec + hmac-md5 and tcp md5sig. OK henning@ and hshoexer@
