AES Command - Technical Specifications



AES Command

Features
  • Operates as AES Protect or AES Metal, command line driven
  • Encrypt single files using a passphrase, or input an initialization vector and key directly
  • Portable, no installation required
  • Written in x86 assembly language
  • Lightweight, only 28k in size
  • Advanced Encryption Standard - Rijndael cipher
  • Passphrase up to 512 characters (AES Protect)
  • PBKDF2 SHA-256 key derivation, 524288 rounds (AES Protect)
  • Automatic AES-NI hardware acceleration
  • Pseudo Random Number Generator, multiple size outputs from 64MB to 16GB
  • PKCS7 padding (AES Metal)
  • Import initialization vector and key from a file in binary (AES Metal)
  • Verify the output against the NIST test vectors (AES Metal)

Operating as AES Protect - 45 byte file header
  • 1 byte. Header version number
  • 12 bytes. Counter
  • 16 bytes. Unique salt for PBKDF2
  • 16 bytes. GCM authentication tag
  • Encrypted data to EOF

Operating as AES Metal - 3 key sizes
  • 128 bits
  • 192 bits
  • 256 bits

Operating as AES Metal - 7 modes of operation
  • Counter, CTR
  • Galois Counter, GCM
  • Output Feedback, OFB
  • Cipher Feedback (128), CFB
  • Cipher Block Chaining, CBC
  • Electronic Codebook, ECB
  • Propagating Cipher Block Chaining, PCBC

Operating as AES Metal - No file header
  • Encrypted data is saved "as is"

Operating as AES Metal - Galois Counter Mode Authentication Tag
  • An Authentication Tag will be prefixed to the encrypted output. This tag is verified when decrypting
  • GCM is the only mode that can verify your files have been successfully decrypted

Requirements
  • CPU with MMX and SSE2
  • Windows XP, Vista, 7, 8, 10. 32 or 64 bits
