Base64 binary encoding mechanics
Base64 represents binary data in an ASCII string format by translating 24 bits of input into four 6-bit Base64 digits from a 64-character index.
Cryptographic hash irreversibility
SHA-256 and SHA-512 are one-way cryptographic hash functions producing fixed-length 256-bit and 512-bit hexadecimal digests for integrity verification.

FAQ
Can I decode a SHA-256 hash back to plain text?
No. Cryptographic hashes are one-way mathematical functions and cannot be reversed.
What is URL-safe Base64?
URL-safe Base64 replaces '+' with '-' and '/' with '_' to prevent URL parameter escaping conflicts.
Is the Base64 & Crypto Hash Encoder / Decoder free?
Yes. It runs in your browser with no account required.
