Fix wrong description

[polRk]

Remove base64 requirements for ciphertext in SymmetricDecryptRequest.

When I submit ciphertext encoded in base64, I get an error message

rpc error: code = InvalidArgument desc = Bad ciphertext

In raw format, after - OK

Full code

typeYCKMSstruct {
sdk*ycsdk.SDKkeyIDstring
}
funcNew(sdk*ycsdk.SDK, keyIDstring) KMS {
return&YCKMS{sdk: sdk, keyID: keyID}
}
func (s*YCKMS) Encrypt(aadContextstring, plaintextstring) (keyIDstring, versionIDstring, ciphertext []byte, errerror) {
aadContextBuf:=make([]byte, base64.RawStdEncoding.EncodedLen(len([]byte(aadContext))))
plaintextBuf:=make([]byte, base64.RawStdEncoding.EncodedLen(len(plaintext)))
base64.RawStdEncoding.Encode(aadContextBuf, []byte(aadContext))
base64.RawStdEncoding.Encode(plaintextBuf, []byte(plaintext))
result, err:=s.sdk.KMSCrypto().SymmetricCrypto().Encrypt(context.Background(), &kms.SymmetricEncryptRequest{
KeyId: s.keyID,
AadContext: aadContextBuf,
Plaintext: plaintextBuf,
})
iferr!=nil {
return"", "", nil, err
}
returnresult.KeyId, result.VersionId, result.Ciphertext, nil
}
func (s*YCKMS) Decrypt(aadContextstring, ciphertext []byte) ([]byte, error) {
aadContextBuf:=make([]byte, base64.RawStdEncoding.EncodedLen(len([]byte(aadContext))))
// ciphertextBuf := make([]byte, base64.RawStdEncoding.EncodedLen(len(ciphertext)))base64.RawStdEncoding.Encode(aadContextBuf, []byte(aadContext))
// base64.RawStdEncoding.Encode(ciphertextBuf, ciphertext)result, err:=s.sdk.KMSCrypto().SymmetricCrypto().Decrypt(context.Background(), &kms.SymmetricDecryptRequest{
KeyId: s.keyID,
AadContext: aadContextBuf,
Ciphertext: ciphertext, })
iferr!=nil {
returnnil, err
}
returnresult.Plaintext, nil
}

Usage

keyID, versionID, ciphertext, err:=k.Encrypt(Bot.ID, Bot.Token)
iferr!=nil {
panic(fmt.Errorf("cannot encrypt Bot.Token: %w", err))
}
plaintext, err:=k.Decrypt(Bot.ID, Bot.TokenCiphertext)
iferr!=nil {
panic(fmt.Errorf("cannot dencrypt Bot.Token: %w", err))
}
plaintext, _=base64.RawStdEncoding.DecodeString(string(plaintext))
fmt.Println(string(plaintext))
