🚀 Installation

Prerequisites

• Go 1.24.0 or later
• Git

Build from Source

git clone https://github.com/ebrasha/abdal-4iproto-server-ssh-keygen.git
cd abdal-4iproto-server-ssh-keygen
go mod tidy
go build -o abdal-4iproto-server-ssh-keygen .

📖 Usage

Interactive Mode (Recommended)

Simply run the program without any arguments:

./abdal-4iproto-server-ssh-keygen

What happens:

1. 🔐 Algorithm Selection: Choose encryption algorithm (RSA, ED25519, or ECDSA)
   • Use ↑/↓ arrow keys or j/k to navigate
   • Press Enter or Space to select
   • Press q to quit
2. 🔍 Checks for existing key files
3. ⚠️ Shows confirmation dialog if files exist
4. 📊 Displays beautiful progress bar during generation
5. ✅ Shows success message with file details
6. ⌨️ Waits for any key press to exit

Algorithm Selection Navigation:

• ↑ or k: Move selection up
• ↓ or j: Move selection down
• Enter or Space: Select algorithm
• q: Quit program

Non-Interactive Mode

Use command line arguments for automation:

# Generate RSA key (default)
./abdal-4iproto-server-ssh-keygen -t rsa -b 4096

# Generate ED25519 key
./abdal-4iproto-server-ssh-keygen -t ed25519

# Generate ECDSA key with P-256
./abdal-4iproto-server-ssh-keygen -t ecdsa -b 256

# Generate ECDSA key with P-384
./abdal-4iproto-server-ssh-keygen -t ecdsa -b 384

# Generate key with custom filename
./abdal-4iproto-server-ssh-keygen -t ed25519 -f my_key

# Generate key with comment
./abdal-4iproto-server-ssh-keygen -t ecdsa -b 521 -C "[email protected]"

# Force overwrite existing files
./abdal-4iproto-server-ssh-keygen -t rsa -b 2048 -force -f existing_key

Command Line Options

Flag	Description	Default	Example
-t	Key type/algorithm: rsa, ed25519, or ecdsa	rsa	-t ed25519
-b	Key size in bits (RSA: 2048,3072,4096,8192 | ECDSA: 256,384,521)	4096	-b 2048
-f	Output filename for private key (auto-named if not specified)	id_rsa/id_ed25519/id_ecdsa	-f my_key
-C	Key comment	""	-C "user@host"
-force	Overwrite existing files	false	-force

🔐 Supported Encryption Algorithms

The tool supports multiple encryption algorithms:

RSA (Rivest-Shamir-Adleman)

• Key Sizes: 2048, 3072, 4096, 8192 bits
• Default: 4096 bits
• Best For: Maximum compatibility with older systems
• File Names: id_rsa / id_rsa.pub

ED25519 (Edwards-curve Digital Signature Algorithm)

• Key Size: 256 bits (fixed)
• Best For: Modern systems, fast and secure
• File Names: id_ed25519 / id_ed25519.pub

ECDSA (Elliptic Curve Digital Signature Algorithm)

• Key Sizes: P-256, P-384, P-521
• Default: P-256
• Best For: Modern systems, efficient and secure
• File Names: id_ecdsa / id_ecdsa.pub
