Cryptographic Signatures vs Message Authentication Codes

Developers should learn cryptographic signatures when building systems requiring data integrity, non-repudiation, or authentication, such as in secure APIs, digital contracts, software distribution, or blockchain applications meets developers should learn and use macs when building secure systems that require data integrity and authentication, such as in network protocols (e. Here's our take.

Cryptographic Signatures

Nice Pick

Developers should learn cryptographic signatures when building systems requiring data integrity, non-repudiation, or authentication, such as in secure APIs, digital contracts, software distribution, or blockchain applications

Pros

• They are essential for implementing features like message signing in email (e
• Related to: public-key-cryptography, hash-functions

Cons

• Specific tradeoffs depend on your use case

Message Authentication Codes
