Picugen is a cryptographic and non-cryptographic hash/checksum generator written in Go. It can be used to easily obtain digests of strings and files using a large variety of algorithms including MD5, SHA-1, and SHA-256. Usage: picugen [-a <algorithm>] [-salt <salt>] [-s <string to hash>] / <file(s) to hash> Examples: picugen -a md5 document.txt Generate MD5 digest of a file picugen -a md5 * Generate MD5 digests of all files in folder picugen -a sha1 -s hello world Generate SHA-1 digest of a string picugen -a sha1 -salt s4lt -s hello world Generate salted SHA-1 digest of a string picugen -a hmacsha1 -k k3y -s untouched Generate HMAC of a string using SHA-1 Available algorithms (default is SHA-256): adler32 Adler-32 checksum (RFC 1950) crc32 32-bit cyclic redundancy check (CRC-32) checksum (defaults to IEEE polynomial) crc32castagnoli CRC-32 using the Castagnoli polynomial (0x82f63b78) crc32ieee CRC-32 using the IEEE polynomial (0xedb88320) crc32koopman CRC-32 using the Koopman polynomial (0xeb31d82e) crc64 64-bit cyclic redundancy check (CRC-64) checksum (defaults to ISO polynomial) crc64ecma CRC-64 using the ECMA polynomial (0xC96C5795D7870F42) crc64iso CRC-64 using the ISO polynomial (0xD800000000000000) fnv FNV-1 non-cryptographic hash (defaults to fnv32) fnv32 32-bit FNV-1 fnv32a 32-bit FNV-1a fnv64 64-bit FNV-1 fnv64a 64-bit FNV-1a hmac Keyed-Hash Message Authentication Code (HMAC) (requires -k <key>) (defaults to SHA-256) hmacmd5 HMAC using MD5 (requires -k <key>) hmacsha1 HMAC using SHA-1 (requires -k <key>) hmacsha256 HMAC using SHA-256 (requires -k <key>) hmacsha512 HMAC using SHA-512 (requires -k <key>) md4 MD4 hash (RFC 1320) md5 MD5 hash (RFC 1321) ripemd160 RIPEMD-160 hash sha1 SHA-1 hash (RFC 3174) sha224 SHA-224 hash (FIPS 180-2) sha256 SHA-256 hash (FIPS 180-2) sha384 SHA-384 hash (FIPS 180-2) sha512 SHA-512 hash (FIPS 180-2) Note: For complex strings, put the string in a file, then run Picugen on the file. (Don't add newlines to the file as they will alter the output.) Sample output: # picugen /bin/bash 664c1834f30f83c97f48b1f364b8368bb0c9949a8fedd29413bb16d70a6e41c6 /bin/bash # picugen -salt s3cr3t -s p4ssw0rd bcd4a8f23d02931039f0296ca6164f3942b1629b12001bc8e6ffec4df8884848 # picugen -a md5 /etc/*.conf 2081f795b0f92490c1c3f00b964e36de /etc/adduser.conf 7f4c49e01e0a23d2f4b20eeb32e95abb /etc/blkid.conf 9c7fa15fd6d8f34a0267101f051f107b /etc/ca-certificates.conf 8c0619be413824f1fc7698cee0f23811 /etc/debconf.conf 527e6a57d0bc9f7c1b1aca2071f3da00 /etc/deluser.conf 7e84402ab9129df85117336840b3d78f /etc/ffserver.conf 629c0e2f8276b26c29b95f7ed53074d7 /etc/gai.conf ca3e32b09c7bfda7e7e3580a587e3c2b /etc/hdparm.conf 89408008f2585c957c031716600d5a80 /etc/host.conf 4cdcca89f13642d97f1044c647d19e2e /etc/insserv.conf f41f22e0d7f16d43f59f682c78224348 /etc/kernel-img.conf 6fb908bd3381b55ee942b261a701aea4 /etc/kerneloops.conf 4317c6de8564b68d628c21efa96b37e4 /etc/ld.so.conf ... # picugen -a hmacsha1 -k 0r4cl3 -s this message is verifiable with the key 15dabc3b4c2cc60c216970a0723f24a3ffc4d4ca
