Util

• Base2N V0.38: General base 2**N conversion routines (N=1...6)
• Bitarray V0.17: Bit array context with max. 524160 bits (spin off from mpint 16 bit prime sieve)
• BTypes V0.12: Common basic type definitions
• Compvers V0.18: Compiler version as string or symbol
• Dates V0.33: Implements compiler and OS independent routines for the current date and time (including milliseconds since midnight) and functions for Julian day numbers.
• Fio V0.15: File IO with $I- and Err variable (without try/finally), simple wrapper calls for system routines.
• Hrtimer V0.23: Contains a high resolution timer for most Pascal/Delphi compilers using the comp data type. It uses the RDTSC instruction, therefore it will stop on machines that do not support RDTSC (this feature can be turned off via $ifdef). The timer is used by several optimizing test programs.
• Mem_util V0.94: Implements compiler independent routines for comparing memory blocks and converting memory blocks to HEX and Base64 strings.
• Ministat V0.43: Statistics unit with accurate "on the fly" statistics routines for one and two variables.
• Sort V1.18: General QuickSort, HeapSort (standard and bottom-up), CombSort routines using swap/compare functions. Additional pointer versions have a typeless data pointer that is carried through the functions and can be used to access local data etc by the caller.
• Tsc V0.35: This unit has a more low level access to the Time Stamp Counter than hrtimer and additionally defines a system dependent low resolution counter (GetTickCount, 18.2 Hz Systick, or milliseconds since midnight) if RDTSC support is not available.

PRNG

• Bob Jenkins' public domain ISAAC random number generator (Indirection, Shift, Accumulate, Add, and Count). The average cycle length of ISAAC is 2**8295, the minimum length is 2**40.
• salsar is based upon the Salsa20 stream cipher and needs the salsa20 unit from salsa_2006-05-07.zip. The core routine uses 128 bit keys and 8 rounds (this default value can be changed to 12 or 20 rounds with salsar_set_rounds).
• aesr uses routines from aes_YYYY-MM-DD.zip in CTR mode with 128 bit key.

procedure generic_init(var ctx: generic_ctx; seed: longint);
  {-Init context from seed}

procedure generic_init0(var ctx: generic_ctx);
  {-Init context from randseed}

procedure generic_next(var ctx: generic_ctx);
  {-Next step of PRNG}

procedure generic_read(var ctx: generic_ctx; dest: pointer; len: longint);
  {-Read len bytes from the PRNG to dest}

function  generic_long(var ctx: generic_ctx): longint;
  {-Next random positive longint}

function  generic_word(var ctx: generic_ctx): word;
  {-Next random word}

function  generic_double(var ctx: generic_ctx): double;
  {-Next random double [0..1) with 32 bit precision}

function  generic_double53(var ctx: generic_ctx): double;
  {-Next random double in [0..1) with 53 bit precision}

function  generic_selftest: boolean;
  {-Simple self-test of PRNG}

MPArith

• New functions: mp_ahex, mp_cornacchia, mp_cornacchia4, mp_crt_setup, mp_crt_setupf, mp_crt_single, mp_crt_solve, mp_gcd1, mp_hex, mp_i2pchar, mp_invmodf, mp_is1a, mp_not_init_multi, RSA/CRT: mp_pkcs1v15_decrypt2, mp_rsadp2, mp_rsa_calc_d, mp_rsa_calc_npq, mp_rsa_calc_private, mp_rsa_clear_private, mp_rsa_init_private, mp_rsa_keygen2
• Changed functions: Improved carry propagation in s_mp_add_d and s_mp_sub_d; mp_is* routines return false if mp_error<>MP_OKAY.
• Other: updated mp_calc, t_calc, t_rcalc sources
• Bugfixes: mp_is_square2 (psqrt^ := a if a=0 or 1); mp_mod_d (for a < 0)
