EOF while attempting go-pgp

Question

I need to pgp encrypt a string in Go and I read that this library was good: "github.com/jchavannes/go-pgp/pgp"

main.go

package main

import "fmt"

func main() {
    encrypted := encrypt("4007400000000007", "123")
    fmt.Println(encrypted)
}

encrypt.go

package main

import (
    "fmt"

    "github.com/jchavannes/go-pgp/pgp"
)

func encrypt(ccNum string, cvv string) string {
    sourceString := `{"cardNumber":"` + ccNum + `","cvv":"` + cvv + `"}`
    fmt.Println(sourceString)
    pubEntity, err := pgp.GetEntity([]byte(TestPublicKey), []byte{})
    if err != nil {
        panic(err.Error())
    }

    encrypted, err := pgp.Encrypt(pubEntity, []byte(sourceString))
    if err != nil {
        panic(err.Error())
    }

    return string(encrypted)
}

-----END PGP PUBLIC KEY BLOCK-----`

When I run the code I get:

{"cardNumber":"4007400000000007","cvv":"123"}
panic: EOF

goroutine 1 [running]:
main.encrypt({0x561363?, 0x60?}, {0x55f3af?, 0x0?})
        /home/peter/Documents/go-projects/circle-pgp-driver/encrypt.go:14 +0x196
main.main()
        /home/peter/Documents/go-projects/circle-pgp-driver/main.go:6 +0x31

Any idea what causes this panic?

Had faced similar issue, was solved by putting a new line after -----BEGIN PGP PUBLIC KEY BLOCK----- in the key string, looks similar for your case.

like

const TestPublicKey = `-----BEGIN PGP PUBLIC KEY BLOCK-----
