AesBridge is a modern, secure, and cross-language AES encryption library. It offers a unified interface for encrypting and decrypting data across multiple programming languages. Supports GCM, CBC, and legacy AES Everywhere modes.

This is the GO implementation of the core project.
👉 Main repository: https://github.com/mervick/aes-bridge

• 🔐 AES-256 encryption in GCM (recommended) and CBC modes
• 🌍 Unified cross-language design
• 📦 Compact binary format or base64 output
• ✅ HMAC Integrity: CBC mode includes HMAC verification
• 🔄 Backward Compatible: Supports legacy AES Everywhere format

• Encrypt(data any, passphrase any) (string, error)
  Encrypts a string using AES-GCM (default).
  Returns: base64-encoded string.

• Decrypt(ciphertext any, passphrase any) (string, error)
  Decrypts a base64-encoded string encrypted with AES-GCM.

• EncryptGCM(data any, passphrase any) (string, error)
  Encrypts a string using AES-GCM. Returns: base64-encoded string.

• DecryptGCM(ciphertext any, passphrase any) (string, error)
  Decrypts a base64-encoded string encrypted with EncryptGCM.

• EncryptGCMBin(data any, passphrase any) (string, error)
  Returns encrypted binary data using AES-GCM.

• DecryptGCMBin(ciphertext any, passphrase any) (string, error)
  Decrypts binary data encrypted with EncryptGCMBin.

• EncryptCBC(data any, passphrase any) (string, error)
  Encrypts a string using AES-CBC. HMAC is used for integrity verification.
  Returns: base64-encoded string.

• DecryptCBC(ciphertext any, passphrase any) (string, error)
  Decrypts a base64-encoded string encrypted with EncryptCBC and verifies HMAC.

• EncryptCBCBin(data any, passphrase any) (string, error)
  Returns encrypted binary data using AES-CBC with HMAC.

• DecryptCBCBin(ciphertext any, passphrase any) (string, error)
  Decrypts binary data encrypted with EncryptCBCBin and verifies HMAC.

⚠️ These functions are kept for backward compatibility only. Their usage is strongly discouraged in new applications.

• EncryptLegacy(data any, passphrase any) (string, error)
  Encrypts a string in the legacy AES Everywhere format.

• DecryptLegacy(ciphertext any, passphrase any) (string, error)
  Decrypts a string encrypted in the legacy AES Everywhere format.
