Deep dives
Understanding JSON Web Tokens (JWTs)
JSON Web Tokens (JWTs) are vital for securely sharing data, typically composed of a header, payload, and signature. The header specifies the token type, the payload contains the actual data, and the signature serves to verify the authenticity of the token. This structure ensures tamper-evidence, meaning any attempt to alter the data can be easily detected. JWTs are increasingly being utilized in various applications, including digital identity verification, highlighting their significance in securing data transfer.
