Dataweave Cryptography - Mulesoft
- 1. DW Crypto in Mule4
- 2. Introduction • MuleSoft provides multiple functions to encode the Dataweave Transformation fields. • This can be achieved using different kind of algorithms like MD5, SHA1, hashwith, HMAC Binary and so on.
- 3. • To use the crypto module in Dataweave, you should import the Crypto Module in Dataweave as below: Import dw:Crypto Introduction
- 4. Functions Function Name Description MD5 Computes the MD5 hash and transforms the binary result into a hexadecimal lower case string. SHA1 Computes the SHA1 hash and transforms the result into a hexadecimal, lowercase string. hashwith Computes the hash value of binary content using a specified algorithm. HMACBinary Computes an HMAC hash (with a secret cryptographic key) on input content. HMACWith Computes an HMAC hash (with a secret cryptographic key) on input content, then transforms the result into a lowercase, hexadecimal string.
- 5. MD5 Crypto • It Computes the MD5 hash and transforms the binary result into a hexadecimal lower-case string. Required Params Description Content Input Data or content in Binary format.
- 8. SHA1 • It Computes the SHA1 hash and transforms the result into a hexadecimal, lowercase string. Required Params Description Content A Binary input value to encrypt.
- 10. SHA1 - Example
- 11. hashwith • It Computes the hash value of binary content using a specified algorithm. • The first argument specifies the binary content to use to calculate the hash value, and the second argument specifies the hashing algorithm to use.
- 12. • The second argument must be any of the accepted Algorithm names: hashwith Algorithm names Description MD2 The MD2 message digest algorithm as defined in RFC 1319. MD5 The MD5 message digest algorithm as defined in RFC 1321. SHA-1, SHA-256, SHA-384, SHA-512 Hash algorithms defined in the FIPS PUB 180-2. SHA-256 is a 256-bit hash function intended to provide 128 bits of security against collision attacks, while SHA-512 is a 512-bit hash function intended to provide 256 bits of security. A 384-bit hash may be obtained by truncating the SHA-512 output.
- 13. Parameters hashwith Required Params Description Content The binary input content to hash. Algorithm The name of the algorithm to use to calculate the hash value of content. This value is a String. Defaults to SHA-1.
- 16. HMACBinary • It Computes an HMAC hash (with a secret cryptographic key) on input content. Required Params Description Secret The secret cryptographic key (a Binary) used when encrypting the content). Content The input content, a Binary value. Algorithm The hashing algorithm. HmacSHA1 is the default. Valid values depend on the JDK version you are using. For JDK 8 and JDK 11, HmacMD5, HmacSHA1, HmacSHA224, HmacSHA256, HmacSHA384, and HmacSHA512 are valid algorithms. For JDK 11, HmacSHA512/224 and HmacSHA512/256 are also valid.
- 19. HMACWith • It Computes an HMAC hash (with a secret cryptographic key) on input content, then transforms the result into a lowercase, hexadecimal string. Required Params Description secret The secret cryptographic key (a Binary) used when encrypting the content). content The input content, a Binary value. algorithm By default, HmacSHA1 is used. Other valid values are HmacSHA256 and HmacSHA512.
