decrypt bytea string #3

emacielxp · 2021-05-25T13:59:39Z

can help me with the error below:

public key

secret key

those keys are generated with this command:

KotlinPGP.generateKeyPair(
                GenerateKeyData("chave_teste", "[email protected]", "123456", KeyData(2048, Algorithm.RSA), KeyData(2048, Algorithm.RSA))
            )

and retrieved by: keyPair.publicKey and keyPair.secretKey

at postgresql, i used the publickey string to encrypt a text and encode the encrypted result as base64. use this command:
select encode(postgis.pgp_pub_encrypt('string to be encrypted and encoded', postgis.dearmor('public key string')), 'base64')

the result is:
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

when i try to decrypt this use my secret key i receive an error, see below the code used:

val decodedBytes = Base64.decode("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", Base64.DEFAULT)

val decodedString = String(decodedBytes)

val decryptResult = KotlinPGP.decrypt(
                secretKey,
                "123456",
                decodedString
)

decoded string from base64 converted to string (decodedString):
