I want to understand one simple thing, which javascript libraries can be used in suiteScript. Like what’s the dependency client side/ server side?

i wouldnt describe it as simple, but the primary requirement for a library to work in suitescript is that it must not use any global or modules specific to the browsers or node

for example, pdf-to-base64.js uses fetch for browsers

that drastically reduces the chances of this library working in suitescript

Ohh, got it. I think need to work/learn more on this.

In the meantime, do you know any method or any other library that I can use to convert PDF to base 64  inside of suitescript.
I have an API that accepts base64 encoded PDFs.

occasionally you might get away with using more minor node modules like path. bundlers like browserify or webpack have equivalents that they can include in their bundles

your question is honestly a little on the strange side

pdf files in suitescript are represented as base64 already

I saved the base64 image directly and it worked that day.

Do you mean
```fileObj.getContents();```
for a PDF file will return me a base64 encoded string.

Yeah, makes sense <@U5TF1GQ20>. It does give me base64 encoded string.

Can I get the the equivalent of this
`CryptoJS.SHA256(accessKeyStr).*toString*(CryptoJS.enc.HEX);`
without using CryptoJs in SS.

I can see there is
```var hashObj = crypto.createHash({
    algorithm: crypto.HashAlg.SHA256
});```
but it does not accept any string,


Do I need to this further?
```hasObj.update({
    input: inputString,
inputEncoding: encode.Encoding.HEX
});```
 Will they be equivalent then?

you will end up using all methods related to hashes

Do you mean this?
```var finalHash = crypto.createHash({
    algorithm: crypto.HashAlg.SHA256
}).update({
    input: inputString
}).digest({outputEncoding: encode.Encoding.HEX})```


Let me try this , will compare both then.
