Generate HmacSHA1 Password | Convert Binary to Hexadecimal - Support and Troubleshooting

Generate HmacSHA1 Password | Convert Binary to Hexadecimal Issue Generate HmacSHA1 Password creating hash and converting binary hash to hexadecimal.

var mac = new GlideCertificateEncryption; var key = GlideStringUtil.base64Encode(skey); var hash = mac.generateMac(key, "HmacSHA1", "hmac_string"); var digest = new GlideDigest(); hash = GlideStringUtil.base64Decode(hash); var password = digest.getSHA1Hex().toLowerCase();

Cause getSHA1Hex() does not convert Base64 to Hexadecimal. We need to use GlideStringUtil.toHexString(GlideStringUtil.base64DecodeAsBytes(hash)); to get password instead using GlideDigest. But GlideStringUtil.toHexString can be only access from maint users.

Resolution var mac = new GlideCertificateEncryption; var key = GlideStringUtil.base64Encode(skey); var hash = mac.generateMac(key, "HmacSHA1", hmac_string);

var password = toHexString(hash);

function toHexString(base64) { // Decode base64 to binary var binaryData = GlideStringUtil.base64DecodeAsBytes(base64); // Convert binary to hexadecimal var hex = ''; for (var i = 0; i var byteValue = binaryData[i]; var hexString = ('0' + (byteValue & 0xFF).toString(16)).slice(-2); // Convert byte to hexadecimal hex += hexString; } return hex; }
