FPLLL(1)

💖 FPLLL 💖

okay bestie, welcome to fplll — the manual page, page 1 of section 1, and yes it's giving ✨lattice cryptographer✨ and honestly? we ate.

🌸 NAME 🌸

fplll — bestie, fplll applies LLL, BKZ or SVP on a given set of row vectors (either from stdin or in a file given as parameter). that's the whole vibe 💅

🎀 SYNOPSIS 🎀

fplll [options] [file]

🦋 DESCRIPTION 🦋

ngl, if you want the full lore, go read /usr/share/doc/libfplll-dev/README.md.gz from the libfplll-dev package. that's where the details live, iykyk.

✨ List of options: ✨

• -a [lll|bkz|hkz|svp|sdb|sld|cvp|hlll] — pick your fighter 👑
  • lll = LLL-reduce the input matrix (this is the default, the main character)
  • bkz = BKZ-reduce the input matrix
  • hkz = HKZ-reduce the input matrix
  • svp = compute a shortest non-zero vector of the lattice
  • sdb = reduce the input matrix using the self dual BKZ variant
  • sld = slide reduce the input matrix
  • cvp = compute the vector in the input lattice closest to an input vector
  • hlll = HLLL-reduce the input matrix
• -v — Enable verbose mode. she talks a lot now, and honestly? we support her 🫶
• -nolll — Does not apply the initial LLL-reduction (for bkz, hkz and svp). skipping the warm-up, bold of you 😭
• -c <c> (default: 0.1) — An arbitrary double constant > 0 for HLLL
• -r <size> — Was the number of rows (ignored). bestie she's retired, she's just here vibing, the flag does literally nothing 🙈
• -d <delta> (default: 0.99)
• -delta <delta> (default: 0.99)
• -e <eta> (default: 0.51)
• -eta <eta> (default: 0.51)
• -t <theta> (default: 0.001)
• -theta <theta> (default: 0.001)
• -l <lovasz> — If not zero, use Lovasz's condition, otherwise Siegel's. two queens, pick one 💅
• -f [mpfr|dd|qd|dpe|double|longdouble] — Floating-point type in LLL
• -p <precision> — Floating-point precision (only with -f mpfr). mpfr only, no cap 💀
• -z [mpz|int|long|double] — Integer type in LLL (default: mpz ; long is the same as int)
• -m [wrapper|fast|heuristic|proved] — LLL version (default: wrapper)
• -y — Enable early reduction
• -b <blocksize> — Size of BKZ blocks
• -bkzmaxloops <loops> — Maximum number of full loop iterations
• -bkzmaxtime <seconds> — Stops after <seconds> seconds.
• -bkzautoabort — Stops when the average slope does not decrease fast enough
• -s <filename.json> — Load BKZ strategies from filename
• -bkzghbound <factor> — Multiplies the Gaussian heuristic by <factor> (of float type)
• -bkzboundedlll — Restricts the LLL call
• -bkzdumpgso <file_name> — Dumps the log of the Gram-Schmidt vectors in specified file
• -of [b|c|s|t|u|v|bk|uk|vk] — Output formats.

💖 reminder bestie: this is fplll version 5.3.3, dated September 2020, and it's the FPLLL(1) manual page. slay, periodt. ✨👑💅
