## Related tools

- [Hash Algorithm Comparator](https://elysiatools.com/en/tools/hash-algorithm-comparator): Hash the same input with MD5, SHA-1, SHA-256, SHA-512, BLAKE2b, and BLAKE3 at the same time and compare them side by side: output length, hex/Base64 digest, security status (broken / modern), and a relative speed benchmark. Great for teaching, choosing a hashing algorithm, or sanity-checking checksums.
- [Text Encryptor/Decryptor](https://elysiatools.com/en/tools/text-encryptor-decryptor): Simple text encryption and decryption using various algorithms
- [Windows PE / Linux ELF / Mach-O Binary Header, Section, Import & Export Inspector](https://elysiatools.com/en/tools/windows-pe-linux-elf-mach-o-binary-header-section-import-export-inspector): Upload a PE-COFF (.exe/.dll), ELF or Mach-O binary and parse its headers end to end: DOS/PE signature, COFF machine, optional header (entry point, image base, subsystem, ASLR/NX/CFG), section table with RVA↔offset mapping, import/export directories, ELF program headers and PIE detection, dynamic symbols and DT_NEEDED, Mach-O load commands and dylibs — with cross-architecture annotations and a hex preview.
- [AES Encryption Tool](https://elysiatools.com/en/tools/aes-encryption-tool): Encrypt or decrypt text and files with AES-256-GCM and export IV-based bundles
- [RSA Encrypt / Decrypt](https://elysiatools.com/en/tools/rsa-encrypt-decrypt): Encrypt text with an RSA public key or decrypt ciphertext with the matching private key, using OAEP padding (SHA-1 or SHA-256). Handles long messages by chunking. Keys and data stay local. PKCS#1 v1.5 is intentionally not offered (Node disables it for decryption due to Bleichenbacher attacks).
- [Atbash Cipher](https://elysiatools.com/en/tools/atbash-cipher): Encode and decode text using Atbash substitution cipher (reverses the alphabet)
- [Hash Generator](https://elysiatools.com/en/tools/hash-generator): Generate hash values (MD5, SHA1, SHA256, SHA512)
- [RC4 Stream Cipher](https://elysiatools.com/en/tools/rc4-encryptor): Encrypt and decrypt text using RC4 stream cipher with a key
