Eoyc

    Hex Encoders

    Hexadecimal encoding converts each byte to its two-digit hexadecimal representation.

    hex

    Aliases: hex-encode

    Encodes text to lowercase hexadecimal representation.

    Usage

    echo "hello" | eoyc -e "hex"
# Output: 68656c6c6f

    How It Works

    Each character is converted to its hexadecimal ASCII value:

    • 'h' (104) → 68
    • 'e' (101) → 65
    • 'l' (108) → 6c
    • 'l' (108) → 6c
    • 'o' (111) → 6f

    Examples

    echo "ABC" | eoyc -e "hex"
# Output: 414243

echo "test123" | eoyc -e "hex"
# Output: 74657374313233

    hex-decode

    Decodes hexadecimal strings back to original text.

    Usage

    echo "68656c6c6f" | eoyc -e "hex-decode"
# Output: hello

    Examples

    echo "414243" | eoyc -e "hex-decode"
# Output: ABC

echo "74657374313233" | eoyc -e "hex-decode"
# Output: test123

    Round-Trip Example

    # Encode then decode
original="Hello World"
encoded=$(echo "$original" | eoyc -e "hex")
decoded=$(echo "$encoded" | eoyc -e "hex-decode")

echo "Original: $original"
echo "Encoded: $encoded"
echo "Decoded: $decoded"

    Use Cases

    • Representing binary data in text format
    • Debugging and inspecting byte values
    • Color codes and data serialization
    • Low-level data manipulation

    Chaining with Hex

    # Hex encode then Base64
echo "data" | eoyc -e "hex>base64"

# Hash then hex encode (redundant since most hashes already output hex)
echo "data" | eoyc -e "sha256>hex"
