19 7z also supports AES-256 based encryption.

63 UNIX/Linux version
64 ------------------
65 There are several otpions to compile 7-Zip with different compilers: gcc and clang.
66 Also 7-Zip code contains two versions for some critical parts of code: in C and in Assembeler.
67 So if you compile the version with Assembeler code, you will get faster 7-Zip binary.
69 7-Zip's assembler code uses the following syntax for different platforms:
71 1) x86 and x86-64 (AMD64): MASM syntax.
72 There are 2 programs that supports MASM syntax in Linux.
74 cpu instructions used in 7-Zip.
75 So you must install Asmc Macro Assembler in Linux, if you want to compile fastest version
76 of 7-Zip x86 and x86-64:
79 2) arm64: GNU assembler for ARM64 with preprocessor.
80 That systax of that arm64 assembler code in 7-Zip is supported by GCC and CLANG for ARM64.
82 There are different binaries that can be compiled from 7-Zip source.
84 makefile - that can be used for compiling Windows version of 7-Zip with nmake command
85 makefile.gcc - that can be used for compiling Linux/macOS versions of 7-Zip with make command
87 At first you must change the current folder to folder that contains `makefile.gcc`:
91 Then you can compile `makefile.gcc` with the command:
93 make -j -f makefile.gcc
96 7-Zip binaries with optimized code and optimzing options.
98 To compile with GCC without assembler:
100 make -j -f ../../cmpl_gcc.mak
103 make -j -f ../../cmpl_clang.mak
105 To compile 7-Zip for x86-64 with asmc assembler:
106 make -j -f ../../cmpl_gcc_x64.mak
108 To compile 7-Zip for arm64 with assembler:
109 make -j -f ../../cmpl_gcc_arm64.mak
111 To compile 7-Zip for arm64 for macOS:
112 make -j -f ../../cmpl_mac_arm64.mak
121 Also you can use p7zip (port of 7-Zip for POSIX systems like Unix or Linux):

370 increase the compression ratio on 5-10% for code for those CPU ISAs:
371 x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.
376 7-Zip commands (example for ARM code):
378 7z a a1.7z a.bin -m0=lzma
380 With filter for little-endian ARM code:
381 7z a a2.7z a.bin -m0=arm -m1=lzma
396 For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.
