Generate Random text using Salesforce Apex

InfallibleTechie Admin

Check the following sample apex code which generates random 10 characters using EncodingUtil.base64Encode(), Crypto.generateAesKey(), replaceAll() and substring() methods.

Sample Apex Code:

String tempKey = EncodingUtil.base64Encode(
    Crypto.generateAesKey(256)
);
tempKey = tempKey.replaceAll( '[+/=]', '');
System.debug(
    tempKey.substring(0, 10)
);

Crypto.generateAesKey() – It is used to generate an Advanced Encryption Standard (AES) key.
EncodingUtil.base64Encode() – It is used to convert the AES key Blob value to an unencoded String representation.
replaceAll() – Replaces +, / and = characters.
substring() – It is used to get the 10 characters.
