$ hashit md5 myfile.txt          # Hash a file: 5d41402abc4b2a76b9719d911017c592
$ echo "data" | hashit sha1 -    # Hash stdin: a17c9aaa61e80a1bf71d0d850af4e5baa9800bbd
$ hashit blake2 "secret data"    # BLAKE2 hash (modern, fast algorithm)
$ hashit crc32 "integrity check" # CRC32 checksum: 3632233996

Password Hash Functions (with salt):

$ hashit bcrypt "password123"       # Bcrypt hash: $2b$12$LQv3c1yqBWVHxkd0LHAkCOYz6TtxMQJqhN8/LewdBXFhAsC/HjBKS
$ hashit argon2 "password123"       # Argon2id hash: $argon2id$v=19$m=4096,t=3,p=1$salt$hash
$ hashit sha256crypt "password"     # SHA-256 crypt: $5$saltvalue$hashvalue
$ hashit sha512crypt "password"     # SHA-512 crypt: $6$saltvalue$hashvalue
$ echo "mypassword" | hashit bcrypt - # Hash password from stdin

Supported Hash Types:

• Simple hashes: md5, sha1, sha224, sha256, sha384, sha512, blake2, sha3, crc32
• Password hashes: bcrypt, argon2, sha256crypt, sha512crypt

Password hashes automatically include random salt and produce different outputs each time for security.

🎲 Entropy Calculator (entropy)

Calculate Shannon entropy for strings, files, or stdin to measure randomness/complexity:

$ entropy "hello world"          # Calculate entropy of string
$ entropy passwords.txt          # Calculate entropy of file contents
$ echo "random data" | entropy - # Calculate entropy of stdin

Entropy values range from 0 (completely predictable) to ~8 (maximum randomness for byte data).

🔄 String/Data Converter (strconv)

Convert between different data encodings and representations:

$ strconv hex "hello"              # Encode to hex: 68656c6c6f
$ strconv hex-decode "68656c6c6f"  # Decode hex: hello
$ strconv base64 "hello world"     # Encode to Base64: aGVsbG8gd29ybGQ=
$ strconv b64-d "aGVsbG8gd29ybGQ="  # Decode Base64: hello world
$ strconv bin 255                  # Integer to binary: 11111111
$ strconv bin "A"                  # String to binary: 01000001
$ echo "data" | strconv hex -      # Encode stdin to hex
$ cat file.txt | strconv base64 -  # Encode file to Base64

Supports:

• Hexadecimal: hex (encode), hex-decode/hex-d (decode)
• Base64: base64/b64 (encode), base64-decode/b64-d (decode)
• Binary: bin/binary (integers to binary numbers, strings to ASCII binary)

🔢 Number Base Converter (numconv)

Convert numbers between different bases (2-36) with auto-detection:

$ numconv 255                    # Auto-detect: 255 (decimal) = 0xff (hex) = 0o377 (octal) = 0b11111111 (binary)
$ numconv 0xff                   # Hex to all: 0xff = 255 (decimal) = 0o377 (octal) = 0b11111111 (binary)
$ numconv 0b1010                 # Binary to all: 0b1010 = 10 (decimal) = 0xa (hex) = 0o12 (octal)
$ numconv 777 8                  # Convert 777 from base 8: 777₈ = 511 (decimal)
$ numconv 255 16                 # Convert 255 to base 16: 255 = ff₁₆
$ numconv abc 16 2               # Convert abc from base 16 to base 2: abc₁₆ = 101010111100₂

Range conversion (convert multiple consecutive numbers):

$ numconv 100-110 hex            # Convert 100-110 to hex: 64, 65, 66, ..., 6E
$ numconv 0x10-0x1F dec          # Convert hex 10-1F to decimal: 16, 17, ..., 31
$ numconv 8-12 bin               # Convert 8-12 to binary: 1000, 1001, ..., 1100
$ numconv 250-255 hex            # Convert 250-255 to hex: FA, FB, FC, FD, FE, FF

Range format supports the same base auto-detection and supports up to 1000 numbers per range.
