Output as hex, decimal or binary. Accepts plain text (UTF-8) or raw bytes via hex/base64 input. - [Data URI Generator](https://elysiatools.com/en/tools/data-uri-generator): Convert files into Data URIs (Base64 or percent-encoded) for inlining images, fonts, and assets directly into HTML, CSS, or Markdown - [Digital Signature Generator](https://elysiatools.com/en/tools/digital-signature-generator): Sign a message with a private key or verify a signature with a public key — supports RSA-PSS (SHA-256), ECDSA (P-256), and Ed25519. Pure client-side crypto (Node crypto.createSign/createVerify), no network. Paste a PEM key to sign or to verify a base64 signature. This tool signs/verifies; it does not generate key pairs. - [Ed25519 / X25519 Keygen and Signature Verifier](https://elysiatools.com/en/tools/ed25519-x25519-keygen-signature-verifier): Generate Ed25519 or X25519 keypairs from random or deterministic seed text, then sign or verify messages - [Excel Field-Level Decryptor](https://elysiatools.com/en/tools/excel-field-decryptor): Decrypt specific fields in Excel files using various decryption methods to restore encrypted information - [Excel Field-Level Encryptor](https://elysiatools.com/en/tools/excel-field-encryptor): Encrypt specific fields in Excel files using various encryption methods to protect sensitive information - [Field-Level Data Decryptor](https://elysiatools.com/en/tools/field-decryptor): Decrypt specific fields in CSV data using various decryption methods to restore encrypted information - [Field-Level Data Encryptor](https://elysiatools.com/en/tools/field-encryptor): Encrypt specific fields in CSV data using various encryption methods to protect sensitive information - [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. - [Image to Base64 Converter](https://elysiatools.com/en/tools/image-to-base64): Convert images to Base64 encoding with support for various formats and quality settings - [Secure Random Generator](https://elysiatools.com/en/tools/secure-random-generator): Generate cryptographically secure random key material driven by entropy budget — request N bits of entropy, get hex/base64/base64url output. Also supports custom-alphabet strings via crypto.randomInt (rejection-sampled, no modulo bias). Use this instead of Math.random()-based tools for any secret/key/token. - [Text Encryptor/Decryptor](https://elysiatools.com/en/tools/text-encryptor-decryptor): Simple text encryption and decryption using various algorithms ## Related content - [Encryption](https://elysiatools.com/en/tags/encryption): Use 40 online encryption tools for encrypting, decrypting, and working with cipher, AES, and RSA data in your browser. - [AES](https://elysiatools.com/en/tags/aes): Browse 5 AES tools in your browser. Processing runs on Elysia Tools servers; text inputs are not stored and uploaded files are deleted after 6 hours. - [Conversion](https://elysiatools.com/en/tags/conversion): Browse 369 online conversion tools for transforming data and files between supported formats.
