## What is DevCipher?

DevCipher is a minimalist, ready-to-use encryption and decryption toolkit designed specifically for developers. It integrates industry-standard hash calculations, symmetric encryption, asymmetric encryption, digital signatures, and common encoding/decoding functions to solve fragmented data security needs in daily development and debugging.

Core Features:
  - Hash Calculation: Supports MD5, SHA-1, SHA-256, SM3, and more for quick text digest generation.
  - Symmetric Cipher: Supports AES, DES, 3DES, SM4 with various block modes and padding options.
  - **Asymmetric Cipher: Supports RSA and SM2 for secure encryption, decryption, and digital signing.
  - **Encoding Tools: High-performance Base64 converter, URL encode/decode, and Bcrypt validation.
  - Premium Experience: Built with native SwiftUI, supports Dark Mode, and fully optimized for iPhone and iPad.
  - Privacy First: All operations are performed strictly locally. No data is ever collected or uploaded.
