Apex Encoding And Crypto

type:integration
Use when Apex must sign, verify, encrypt, hash, encode, or decode payloads — including HMAC for webhook signatures, RSA/ECDSA signing for JWT bearer flows, AES for stored secrets, base64/hex/URL encoding, and digest comparisons for integration integrity. Triggers: 'Crypto.sign', 'Crypto.generateMac', 'EncodingUtil.base64Encode', 'JWT signing in Apex', 'verify webhook signature'. NOT for setting up Named Credentials or OAuth flows end-to-end — use apex-named-credentials-patterns; NOT for SOQL injection defense — use soql-security.
