Licrypt

Tuned for speed, security, and performance: Licrypt performs at 400 nanoseconds per operation with just 8 allocations, handling over 3 million loops in just one second! ⚡️📊

• Symmetric cryptography made easy
• Securely encrypt and decrypt
• Data authenticity and integrity
• Performant: 400ns/op & 8 allocs tested in parallel

Install PKG

go get github.com/SimpaiX-net/licrypt

Current implementations

• AES CTR

  In the form of hmac|iv|cipher, HMAC provides authenticity and integrity over iv + cipher as AES CTR is not solely secure

• AES GCM - Endorsed: Highly efficient

  The GCM algorithm provides both data authenticity (integrity) and confidentiality therefore no HMAC is required
